Calculate 3dB Bandwidth and Cutoff Frequency
Calculator finds 3dB Bandwidth and Cutoff Frequency for selected values.
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.

Where,
BW=Bandwidth of a circuit in unit of frequency,
fo=center frequency,
f2=the upper cut off frequency,
f1=the lower cut off frequency
