发明名称 REPRODUCTION CIRCUIT ARRANGEMENT HAVING A NOISE REDUCTION CIRCUIT AND A GAP DETECTION CIRCUIT
摘要 In a circuit arrangement for reproducing audio information signals recorded in one or a plurality of audio channels on a movable sound carrier, the sound carrier being moved at a normal reproduction speed during reproduction, the arrangement including a noise reduction circuit, each audio channel of the arrangement including an RC network (10, 30) with at least one RC filter, there is provided a gap detection circuit integrated in the reproduction circuit arrangement. This gap detection circuit jointly uses parts of the noise reduction circuit, at least one or a plurality of RC filters of the RC network(s) (10, 30) of the noise reduction circuit, during the time intervals in which gaps in the audio information signals are to be detected by the pause detection circuit when the sound carrier is moved at a higher speed than the normal reproduction speed.
