Abstract

본 발명은 FM, AM 방송의 밴드 구분없이 보다 빠른 시간내에 용이하게 스테레오 방송을 청취할 수 있도록 한 FM/AM수신기에서의 스테레오 방송 자동선국 및 자동 기억방법에 관한 것이다.The present invention relates to a stereo broadcast auto-tuning and automatic storage method in an FM / AM receiver, which makes it possible to easily listen to a stereo broadcast within a short time without any band classification of FM and AM broadcasts.

종래의 FM/AM수신기에서의 방송국 선국 및 기억 방법은 스테레오 방법을 선국하기 위해서는 같은 동작을 반복 수행해야만 하는 번거로움괴 한정된 밴드내에서만 기억을 해야 하는 문제점이 있었다.In the conventional FM / AM receiver, the broadcasting station tuning and storage method has a problem in that memory must be stored only in a troublesome limited band in which the same operation must be repeatedly performed in order to tune the stereo method.

이를 개선코자 하여 본 발명은 FM/AM 수신기에서 스테레오음 또는 모노음으로 방송하는 방송국을 구별하여 스테레오음으로 방송하는 방송국의 자동선국 및 자동 기억할 수 있는 방법을 제공코자 한 것으로서, 모든 FM/AM겸용 수신기에 채용 가치가 있다.To improve this, the present invention is to provide a method for automatically tuning and automatically storing a station broadcasting in stereo sound by distinguishing a station broadcasting in stereo or mono sound in an FM / AM receiver. It is worth hiring to the receiver.
