Something new occurred to me regarding your audio… The effect that I presume is clipping, may be caused by echo in the room your recording in, especially is the surfaces are mostly bare. If this is a problem, and you want to fix it, there are a lot of different ways. But a quick one would be to hang some kind of cloth on your walls. Although I have a hunch that filling a large mesh net with packing peanuts, or some other loose, light material, and attaching it to your ceiling would work pretty good. I don't know you opinion on this, so I'm sorry if I seem pushy or something. Just trying to help…

A flash ADC uses comparators with a settling time of 40ns and a 3 stage digital decoder made of gates possessing a delay of 2ns.Determine the conversion time of ADC ?

Sir is ADC and DAC series over for gate syllabus ?
@ALLABOUTELECTRONICS5 жыл бұрын
For gate perspective all the topics have been covered. But I am going to cover other ADCs like sigma- delta and pipeline ADC, and importance of performance parameters of the ADC. I think it will be useful in general to everyone one who are going to use ADC and DAC in some application.

Sir , In the half flash adc ,can we get the first 4bits of the output by directly from the first ADC ?
@ALLABOUTELECTRONICS3 жыл бұрын
Yes, that's exactly how we get the 4 MSBs of output. (As I have mentioned at 9:13)

How it is 1v after R divides by R + 7R
@uditgohil75472 ай бұрын
I'm not getting an output one of the comparator when applying the input voltage of 5volts. Instead of that I'm getting 10volts.

Would you please elaborate how you have connected the circuit?

7 comparators is pretty expensive though!
@ALLABOUTELECTRONICS6 ай бұрын
That is why flash ADCs are not cheap.

@@ALLABOUTELECTRONICS Is it the type we use for signal processing and control? because the delay caused by standard ADC's can distort a real time signal that needs to be processed right then and there because say a temperature signal is a sine wave, it could appear distorted when inputted this way due to the sequential part that varies depending on values.

For the second flash adc onwards it is rather difficult to change to digital (too small) , 8:37

Hi sir, on what basis we should select vref , if my input signal is varying from 2v to 6v
@ALLABOUTELECTRONICS Жыл бұрын
Typically for ADC, the reference voltage is specified in the data sheet. ( like 3.3 v, 5V, 9V, 12V etc)In your case, you need a reference voltage more than 6V. For example, if ADC supports up to 9V, then you can use that voltage. But again that depends on the ADC.

I have a doubt that for this encoder we need 8 inputs but from 7 comparators we are giving 7 inputs to encoder then what about 8th input.

Just look at the diagram of 3 bit flash ADC. It requires 7 comparators.

In our they teach me 8-comparator and 7resister .sir
@ALLABOUTELECTRONICS Жыл бұрын
It is in fact, other way around. Imagine just 1-bit comparator. To compare the voltage, using a voltage divider, you need at least two resistor. That means for 1-bit, you need 1 comparator and 2 resistor. That is 2^1 -1 comparator and 2^1 resistor. The same is true for n-bit flash adc.

Sir, What is sigma delta ADC! Is it another kind of ADC! I haven't found in our channel ALL ABOUT ELECTRONICS!!!
@ALLABOUTELECTRONICS3 жыл бұрын
Yes it's another type of ADC. It is typically used where high resolution is required. ( But speed is not that important). Someday, will also cover that on the channel.
