Abstract

Low frequency tone detector system for stereo phonic receivers. Consists of an input terminal (11) for receiving signals that may comprise a default frequency signal; a very narrow band step filter (10) coupled to the entry terminal (11) to give out only to such signs received at frequency or near the default frequency; of two signal components (12, 14); of a retention circuit (16); of a displacement recorder (18) coupled to the retention circuit (16); of an explorer device (23); and of a retention circuit (24) whose output is coupled by an output terminal (26) to the external circuitery that carries out the detection of the signal.
