I'm working on a small audio project and I need a circuit that does the following: take a signal from an electret mic, rectify the signal, amplify it, and remove the DC offset. I have tried many circuit designs but they are not working fine with me (too much noise and with DC offset). Should I mention that the electret mic's resistant is approximately 2.8 kΩ. Thanks in advance. any help will be appreciated :)
This is what wiki says: -
This will work fine providing you AC couple your microphone to the input and AC couple the output. Simple series capacitance will do the decoupling of the DC signal.
PS it's only half wave rectification shown above.
This is a full wave circuit
