Waveform Shaping Circuit

This is a waveform shaping circuit which provides independent adjustment of pulse rise time and fall time.

The circuit comprises two non interacting RC networks, individually responsive to positive going and negative going voltages. The rise time of positive going voltages is a function of the time constant of the rise time adjustment potentiometer R1 and capacitor C1, with diode D2 shorting out R2. Likewise, the fall time of negative going voltages is a function of the time constant of the fall time adjustment potentiometer R2 and capacitor C1 with diode D1 shorting out R1.
