摘要: An improved AM-FM combined stereo receiver (100) is provided having a single processor (155) for removing, in the FM mode, arctangent distortron, and AM to process phase term from {L - R /1 + L R} determine R/1 R}. Further, radio includes discriminator circuit (161, 137, 139) wherein, tank (137, used convert frequency deviation baseband audio and, as frequency-determining element voltage controlled oscillator (VCO) (161), VCO being translate intermediate (IF) signal baseband.
