Band Pass Filter Circuit Diagram Using Op Amp. Then the op amp is used for the amplification. The first part is for a high pass filter.
The first part is for a high pass filter. Block diagram of active band pass filter. This bandpass filter below is an inverting bandpass filter.
Generally a narrow bandpass filter uses several feedbacks.
The last part of the circuit is the low pass filter. Block diagram of active band pass filter. The below figure shows the circuit diagram of active band pass filter. This bandpass filter below is an inverting bandpass filter.
