ABSTRACT:
In order to distinguish useful electrical signals from noise signals which are superimposed on the useful signals, a time window is moved along the receiver signal by means of a shift register. If within this time window the received signal exceeds a predetermined minimum level for a predetermined period of time, this receiver signal is recognized as being a useful signal.
