<p>A digital signal played back from a record medium (2) is supplied to a plurality of processing circuits (22, 23) which exhibit respectively different characteristics to impart different error rates to the digital signal processed by each circuit (22, 23). The processed digital signal having the most favourable error rate is detected (41, 42) and the processing circuit (22, 23) which produces that signal is selected for use with further circuitry (26, 27, 28) which recovers information from the processed digital signal. <IMAGE> <IMAGE></p> |
