Hi everyone,
I'm stuck this circuit I attached. R136 = R138 = 300 KΩ; R140 = 15 KΩ (R140 connects to GND); C28 = 5100 nF; input is DC signal and output is on the other side of C28. Anyone can help the transfer function this circuit, please. Thank you very much.
To be honest, input signal is generated from phase splitter circuit ( make AC 400 Hz signal to DC signal). I wonder how this circuit affects to DC input signal. As @Bradtherad said, the C28 is useless in this case? or I mean, only the path through R136, R140 divider? The author said that this circuit will have special effect to input. But how? I'm stuck
