ABSTRACT:
A method of masking interruptions in the playback of received radio signals is provided, in which lengthy interruptions are allowed only when modulation of the radio broadcast program currently being received is recognized as speech, and a modulation pause in the received radio signal is detected. This method permits essentially complete masking of lengthy interruptions in playback or making them inaudible, in which these interruptions are necessary, e.g., for analysis/testing for a transmission frequency of transmitted RDS information to be used as an alternative to a transmission frequency currently being received.
