Abstract

A television receiver includes a single tuner for tuning both television channels and broadcast FM stations. The tuner serves as the first conversion stage of a double conversion FM receiver, wherein the mixer of an FM radio integrated circuit serves as the second conversion stage. A single discriminator circuit is employed for tuning FM radio signals having a first deviation, such as broadcast FM radio signals, and FM radio signals having a second deviation, such as signals of the National Weather Service. Circuitry for amplifying the output signal of the discriminator circuit exhibits a first gain when amplifying FM signals having the first deviation, and exhibiting a second gain when amplifying FM signals having the second deviation.
