Abstract
A method and apparatus for high fidelity duplexing, local transmission and reception of audio-signals transmitted from sources such as stereos, televisions, or musical instruments is taught. According to these teachings, high fidelity wireless stereophonic transmission system having a plurality of audio channels are realized. An oscillator is electrically connected to the first audio channel to provide a first carrier frequency upon which the data of the first audio channel is imposed. The first carrier frequency is then combined with a second audio channel's data forming a composite signal. The composite signal is then imposed on signal generated by a second oscillator. This second oscillator provides a carrier frequency for a frequency modulated (FM) transmitter. The signal from the FM transmitter is received by a receiver and the respective signal's of the two audio channels are demodulated and used to drive speakers.
