Assume I have a square wave pulse train, where each high lasts for H and each low lasts for L seconds. I sample this waveform and have the sequence of numbers.
Question is what should be the sampling rate if I just want to know what level I am in(High or Low)?
I know by Nyquist I can find the sampling rate for full-reconstruction of the pulse train, but I don't need the full reconstruction. I just want to be able to:
1. Don't miss any High or Low
2. Detect all Lows and Highs
