ABSTRACT:
A communications receiver squelch circuit for use in frequency modulation systems which has tight squelch sensitivity. The squelch circuit includes two audio limiters and provides improved squelch sensitivity and squelch action that is independent of carrier modulation and significantly minimizes squelch clamping and squelch boost characteristics.
