I have 2 khz square waves with different amplitudes in an analog input. How to can i read those signal's amplitude?

Do you need to detect the amplitude of each cycle of a given 2kHz input or is one 2kHz source going to have fixed amplitude which may be different from another 2kHz source? If it's the latter you might consider a peak detector circuit; allow it to sample 'N' peaks (characterize what number 'N' is t…

Is the base line voltage zero or is it less than zero, a negative voltage?
