Signals are mainly classified into two types i. Digital to analog converter is an electronic circuit that converts any digital signal such as binary signal into an analog signal voltage or current. The DAC converts these bits into an analog voltage or current. The information exist in real world is in analog form. Why we convert them into digital form in the first place if we want to convert them back? But we cannot understand the digital data in real world.
In order to understand the data that we process in a digital domain, we need to convert it into analog domain. We process it using our computers to edit it according to over needs.
The digital binary data exists in the form of bits. The bit weight is multiplied by the bit value. Since the bit could be either 0 or 1, it means. Now adding the weights of all the bits with its value in a binary number. This is how the digital to analog converter DAC works by adding the weights of all corresponding bits with its value to generate the analog value at its output.
The DAC can be designed using one of the following types of circuits. The weighted resistor method utilizes the summing operational amplifier circuit. The summing amplifier adds the input signals with different gains corresponding to their resistors. As we know the V ref the reference voltage or the maximum analog output voltage is the only input signal beside the binary input so.
The resistors are scaled with the values 2 N-1 -nsuch that. The output voltage for a 4 bit binary number would be.
As you can see, each resistor is scaled to add the bit-weight of each bit of a binary input. Simplified formulae for such circuit would be. Where the denominator 2 N-1 represents the scaling factor of each corresponding resistor. These drawbacks can be resolved by using the other method discussed below. There are only two types of resistors used. Working.DVI-D to HDMI Adapter Work?! 
B 2 B 1 B 0 are the 3 bits of the binary input. Then the equivalent circuit would be.
So the output voltage in this case would become. Applying the same process the output voltage will be. As we know the output of the opamp is the sum of individual inputs where each bit is.
We can generalize this formula for an N bit binary number as. Example :. Pulse Width Modulation or PWM is a method of varying the average power of a signal by varying its duty cycle.A component diagram, also known as a UML component diagram, describes the organization and wiring of the physical components in a system. Component diagrams are often drawn to help model implementation details and double-check that every aspect of the system's required functions is covered by planned development.
In the first version of UML, components included in these diagrams were physical: documents, database table, files, and executables, all physical elements with a location. In the world of UML 2, these components are less physical and more conceptual stand-alone design elements such as a business process that provides or requires interfaces to interact with other constructs in the system.
The physical elements described in UML 1, like files and documents, are now referred to as artifacts. A UML 2 component may contain multiple physical artifacts if they naturally belong together. A component is a logical unit block of the system, a slightly higher abstraction than classes. It is represented as a rectangle with a smaller rectangle in the upper right corner with tabs or the word written above the name of the component to help distinguish it from a class.
An interface small circle or semi-circle on a stick describes a group of operations used required or created provided by components. A full circle represents an interface created or provided by the component. A semi-circle represents a required interface, like a person's input. Ports are represented using a square along the edge of the system or a component. A port is often used to help expose required and provided interfaces of a component.

Many thanks to all who have donated. When the circuit is powered by a 9V battery, the LED switches on. A switch or link on the breadboard is closed to start the timer causing the LED to switch off for a time period. After the time period is over, the LED will switch on again.
The following video demonstrates the circuit. Can't see the video? You will need to have completed tutorial one where you would have learned about breadboards, resistors, LEDs and circuit diagrams. Learn about capacitorstransistors and switches before starting this tutorial.
The circuit diagram differs from the circuit diagram of tutorial 1 in that the components now have reference designators assigned to them. Reference designators allow easy reference to the circuit's components - e. They are also used to identify components on a circuit board. Circuit boards will typically have reference designators silk-screened on the board next to each component.
In this way it is easy to find corresponding components on the circuit diagram and the circuit board. The circuit shows that it is to be powered by 9V. The electrolytic capacitor must be connected the correct way around in the circuit - observe the capacitor's polarity. As you learned in tutorial 1, resistors can be connected with either lead to 9V.
Be sure to place the correct value resistor in the correct place in the circuit. We do not need to use an actual switch in the circuit, but can instead use a wire link to act as a switch by plugging it into the breadboard to close the switch or unplugging it to open the switch. The transistor pinout needs to be observed - the collector cbase b and emitter e of the physical transistor must be connected as shown in the circuit diagram.
Take care not to connect any of the transistor pins to the wrong part of the circuit - e. The mapping of the NPN transistor symbol to the physical transistor in a TO package is shown here:. Bend the longer positive lead of the capacitor out to the left and plug it into the breadboard so that there are 5 empty holes tie points between the two capacitor leads.
In the photo the negative lead of the capacitor is on the right. The negative lead is marked on the body of the capacitor. R1 connects to the positive lead of C1, so connect it to a tie point in the same conductive strip of the breadboard. The other lead of R1 connects to the top rail of the breadboard which will be where the positive lead of the battery connects.Welcome to Pinouts.

It was a simple question Thanx again for your help, Thankyou again for the help Any help on these would be V helpfull.
Note that the original VGA standard used pin 9 as a no-connect key. That entire middle row, save for pin 9, is grounds, along with pin 5 on the end of the top row. You will likely be fine without it, but that's what it is, if you need it or if you want to be fully compatible. The DDC clock and data pins will be necessary for plug and play, but manual configuration should be possible without them. Just be sure to plug in all the correct clock and resolution values, or if you go testing, don't let it run for long in bad video modes or you can damage your equipment.
A second or two of testing should be fine, however, as long as the voltages and the like remain video standard -- don't go testing it plugged into the power mains or the like!
At least, that's how it was on my broken adapter. Note that the RGB operating voltages are different than the TTL signaling voltages on the other lines, so keeping the two grounds separate might be wise. However, testing with a meter would likely be wise first, just in case. Good luck! Monitor controls the level. It didn't say, but this would appear to refer to the digital signal. Both of the monitors I have handy here ground both VGA pins 4 and Most seem to ignore it, while some do indeed keep the digital signal off if it's not high.
DVI pinout diagram. The functions of contacts in electrical connectors, be they power- or signaling-related, must be specified in order for connectors to be interchangeable. When connected, each contact of a connector must mate with the contact on the other connector that has the same function.
If contacts of disparate functions are allowed to make contact, the connection may fail and damage may result. Therefore, pinouts are a vital reference when building and testing connectors, cables, and adapters. A female DVI-I socket from the front. Audio and Video Connectors. The pin VGA connector is found on many video cards, computer monitors, and high definition television sets.
On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector. In the original version of DE pinout, one pin was keyed by plugging the female connector hole; this prevented non-VGA 15 pin cables from being plugged into a VGA socket.
The VGA interface is not engineered to be hotpluggable so that the user can connect or disconnect the output device while the host is runningalthough in practice this can be done and usually does not cause damage to the hardware or other problems.
However, nothing in the design ensures that the ground pins make a connection first and break last, so hotplugging may introduce surges in signal lines which may or may not be adequately protected against. Also, depending on the hardware and software, detecting a monitor being connected might not work properly in all cases. VGA connector pinout. The Audio and Video Connectors solution contains a set of video connectors, audio connectors and s video connection; you will also find pre-designed objects, libraries, templates, and samples, allowing quick and easy diagramming of various configurations.
The digital interface is used to connect a video source to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of digital video content. Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets, video game consoles and DVD players.

Video Connectors.The interface is used for connecting display devices to PC or smart unit and it was developed with the intention of creating a standard for transferring digital video content. The DVI connector is used to establish this interface. Although DVI is present in most modern day graphic cards and HD monitors it is gradually being phased out.
But for few years we will see DVI in our life. Since it can run video stream at X pixel with refresh rate of 60Hzthe user can experience high definition gaming and movie experience. As mentioned earlier the pin configuration of three types is different and you have to match the appropriate cable connection or the port will be damaged permanently.

Pinout or pin-out is a term used in electronics to describe how an electrical cable is wired, or the function of each wire pin in a connector. An electrical connector typically consists of several electrical contacts or pins that can be used to carry electrical power or signals. Due to the wide variety of applications and manufacturers, a wide selection of electrical connectors exists with different types and numbers of contacts or pins.
The pinout of a connector identifies each individual pin, which is critical when creating cable assemblies and adapters. Proper identification of pins and wires ensures that the signals and power are transmitted across cables and connectors. AllPinouts Archive of cable and connectors pin-outs.
