摘要
A portable high fidelity tape player and cordless radio telephone system includes a base unit, a handset unit and a stereo unit, in which the stereo unit includes a carrier filter, a carrier receiver, a pilot tone filter, a pilot tone decorder, a modulation circuit, a set of pilot tone oscillators, and a set of integrated circuits. When a ringing signal in the service line enters the base unit while the stereo unit is playing a recording tape, the operation of the motor of the stereo unit stops and the listener is enabled to proceed with the telephone conversation. Upon completing the conversation or after the party at the end of the line has hung up, the stereo unit returns to its operating state and the user may resume listening to the recording tape.
