ABSTRACT:
A buffer system for radio receivers includes a cyclic storage device connectable to a demodulator circuit for continuously storing the audio signals last outputted thereby only over a predetermined time interval, enabling the listener to jump-back to hear a preceding portion of the radio broadcasts. In one described embodiment, the listener normally hears the broadcasts in a real-time manner but may depress a button to hear the broadcasts in a delayed-time manner via the cyclic storage device. In a second described embodiment, the listener normally hears the broadcasts in a real-time manner, may depress a button to freeze a part of the broadcast in another storage device, and may later depress another button to play back the portion frozen.
