摘要：Apparatus and method are presented for broadcasting an RF signal comprisedof analog FM and digital signals. An analog FM source provides an analog FM signal. A
digital source provides a digital signal. A splitter splits the FM signal into a fractionalportion and remainder portion. A summer combines the fractional portion with the digitalsignal to provide a first combined signal. A main FM transmitter amplifies the remainderportion to provide an amplified FM signal. A digital transmitter amplifies the firstcombined signal to provide an amplified combined signal. A combiner combines theamplified FM signal and the amplified combined signal to provide a composite RF signalto be broadcasted.
