Feeding white noise into this bandpass filter gives you a good feeling for the frequency response, at least as well as my ‘scope will capture it. You’ll note that the slopes of the highpass an ...

An electronic circuit that accepts a signal and filters out unwanted frequencies, allowing only a particular frequency or frequency range (band of frequencies) to reach the output side.

Bandpass filter (BPF) is two coupled circuits with capacitive external coupling. There are two modes for cut-off frequency programming: manually or automatically. In automatic mode one of the circuits ...
