ABSTRACT:
A band-pass filter comprising a plurality of coupled electromechanical filters is disclosed. Each electromechanical filter has a frequency pass-band centered about a fundamental frequency and a plurality of higher frequency pass-bands which are centered about overtones of the fundamental frequency. At least one of the electromechanical filters has a fundamental frequency that is different from the other filters and all the filters have a common overtone frequency. The band-pass filter will pass all frequencies falling within the band about the common overtone frequency, while all other frequencies will be suppressed.
