Electronic – RC circuit charging and discharging by square wave not giving a square wave across input on oscilloscope

question shifted to Input across RC circuit is not showing a square wave though the input is a square wave as it was unclear

Best Answer

With the fast edge only being 50% of the input waveform (shown on scope), your generator output resistance is the same value as the R in the RC lowpass. You have an instantaneous voltage divider for the fast edge.
