Abstract

The aim of the invention is to obtain, using digital circuit means, from a binary signal a control quantity (G) which indicates whether the binary signal contains a wanted signal or merely an interference signal. In a first stage (24), the run length is checked and, in a second stage (25, 26), the distance between the run length overruns is monitored. The circuit is of particular use in detecting the beginning of the wanted signal in a digital recorder.
