Calculate 3dB Bandwidth and Cutoff Frequency
Calculator finds 3dB Bandwidth and Cutoff Frequency for selected values.
Please enter the values for Center Frequency and Quality Factor.
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.
BW = fo / Q
BW = f2 - f1
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
