Program discriminating receiver provided with sound recording function

Abstract

Abstract PURPOSE:To record automatically desired information programs and hear only required information or many kinds of information by setting preliminarily required program to be heated in the receiver side. CONSTITUTION:Broadcast information decoded by an FM tuner 2 and an AM tuner 3 is not only outputted from a speaker 5 through an interlocking changeover switch 4 but also inputted to a sound recorder 7. The demodulated output from tuners 2 and 3 is applied to a program discriminating circuit 8, and start and end pattern of special information superposed to a carrier wave or an audio band are detected and are applied to a coincidence detecting circuit 9. A program start code pattern 10 and a program end code pattern 11 set preliminarily by a program selecting switch 12 are applied to this circuit 9, and the coincidence between these set patterns and patterns detected by the circuit 8 is detected. The detection output of the circuit 9 is applied to an FF circuit 13, and the sound recorder 7 is controlled by outputs Q and Q' of the circuit 13 to record desired information programs, and only required information or many kinds of information are heard.
