Abstract

The appts. comprises a component (3) for sampling the fed signal with a determined primary sampling frequency (f1) and converting the sample to digital form. A memory (4) stores the samples in digital form in their time sequence. A device feeds out the memory-stored samples in their time sequence at a feed-out frequency (f2) which is different from that for sampling (f1), the samples are then converted (7) to analogue form. A probe (17) monitors the audio frequency signals for their frequency content, and controls their feed-out frequency based on the result. A periodically activated analogue-digital converter (3) is used to digitise the red audio-frequency signals. The converter is controlled by a primary time pulse series at the sampling frequency (f1) from a clock (2).
