I only know that this part of the circuit generates a sine wave of about 20hz to 50hz. I am not good enough to analyze it from the formula. Please help me with some advice. Thank you.
Does anyone know more about switched capacitor filters? Can you tell me about them? :congratulate: @cruelfox, I saw you talk about filters before. Can you tell me more about this?
