bandpass filter

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. See bandstop filter.

The design parameters of the bandpass filter, i.e., the coupling coefficients and external quality factor can be determined in terms of low-pass prototype filter parameters ([g.sub.1], [g.sub.2], [J.sub.1] and [J.sub.2]) and the relationship between the bandpass design parameters and the low-pass parameters are determined using the formulas below [19].
