I have this circuit for a phase shifter using dual supply. I want to make one for single supply. Below is my take. Any help with supply conversion and phase shift calculations are appreciated. I don't quite understand how the frequency points are chosen. This circuit, if my math is right, has frequency points at:
IC1B= 3386.28Hz
IC1C= 497.98Hz
IC1D= 49.8Hz
IC2B= 13912.15Hz
IC2C= 1396.83Hz
IC2D= 201.56Hz
Thank you
