WebFeb 7, 2024 · Introduction. A Band Pass Filter is a circuit which allows only particular band of frequencies to pass through it. This Pass band is mainly between the cut-off frequencies and they are f L and f H, where f L is the lower cut-off frequency and f H is higher cut-off frequency.. The centre frequency is denoted by ‘f C ’ and it is also called as resonant … http://leleivre.com/rf_butterworth_BPF.html
