A cutoff frequency is a border in a system's frequency response at which energy flowing through the system starts to decrease or reflected without being transmitted.

Formula :

BW = fo / Q

BW = f2 - f1

Where,

BW = Bandwidth of a circuit in unit of frequency,

Q = Quality Factor

fo = center frequency,

f2 = the upper cut off frequency,

f1 = the lower cut off frequency
