I has a question about the digital output of comparator.
Like attached file , the comparator has two output Vo+ and Vo-
Then i want to get the PCM signal , is only get Vo+ to do next step(FFT analysis)?
or get the differential output (Vo+) - (Vo-) to do next step?
I had already checked that , there are have some difference.
Which are the correct output , single ended or differential ?
thanks~~!!
