Crystal bandpass filters
WebThe crystal filter has been a particularly critical element in the development of narrowband communications systems. The desire to send multiple voice messages on a single telephone line resulted in the introduction of carrier telephone systems in 1916. These early systems used LC filters in the 10 to 40 kHz frequency range. WebThe crystal band-pass filter makes it possible to send a great number of simultaneous telephone conversations over a single long-distance line, microwave radio system, or submarine cable, because it separates each voice channel from all …
