digital to analog video converter zero lag

down here this is ground then we start at 1.25, we add 1.25 to 2.5, add 1.25 to 3.75 and so on, up to 8.75 and then there are 10 volts right here. If we took ten divided by eight we would have 1.25, so that would be 1.25 volt increments across these components. That 10 volt is going to be distributed in series across these eight components. It doesn't give you a value of R but all of the R's are the same value. That 10 volts will be spread out across these components. Here we have the overall process, analog to digital and so what we're going to do is start out with 24 volts and we're going to put it across a zener diode here which will regulate to 10 volts. we're introducing the subject and we want to keep it basic. Usually, you would have converters that are much larger than that, maybe 16, 24 or whatever. Now, this is a mighty three-bit converter. We've already mentioned that we have an analog value coming in and our goal is to convert it to a digital output. Let's talk a little bit about this circuit. Now, this particular circuit is called a flash analog to digital converter. An analog voltage or current is applied to the ADC input and is transformed into an equivalent digital value.

Here we would have our analog input and then on A or C, B, and A over here we would have our digital output.Īn analog to digital is the functional opposite of a digital to analog converter. Now, we're going to be looking at the process of taking an analog input and converting it to a digital representation. In the previous section, we looked at digital to analog. We are continuing in 15-4 and in this section, we're looking at analog to digital conversion.
