Dual-signal A-M receiving apparatus

摘要

Receiving apparatus for a modified quadrature A-M dual-signal wave, which samples the input wave and separates and reconstructs the signals in analog form. Superimposed noise in the frequency band of the modulated wave may be substantially reduced in both signals. The signals may be separated adequately to permit reception of a single compatible stereo transmission, or of either one of two different non-compatible mono transmissions on a single carrier, by use of negative-feedback timing loops.
