Abstract: 781,582. Radio receiving circuits; muting. COLE, Ltd., E. K., and BURNARD, C. L. June 3, 1955 [June 4, 1954], No. 16537/54. Class 40 (5), Muting is performed by a diode V1 connected in series between the detector V4 and the audio amplifier. The cathode of the diode V1 is held at a positive potential, derived from a potentiometer VR over resistor R2, while its anode potential is derived from a D.C. amplifier V2, over resistor R7. In the absence of an adequate signal the D.C. amplifier V2 is conductive, its grid being held at near ground potential by means of a potentiometer comprising resistor R3 and clamping diode V3; the anode potential is then low and the anode of the diode V1 negative with respect to its cathode, so that the diode V1 is non-conductive. A sufficient signal produces a negative D.C. potential at the point X which drives the valve V2 to cut-off; its anode potential then rises, bringing the anode of the diode V positive with respect to its cathode and so causing conduction in this diode. The muting level is determined by the potentiometer VR. The diode V3 may be omitted, clamping then being performed' by grid current in the valve V2. The arrangement may also be switched so that (i) the diode V1 is used as a noise limiter of the " series-gapper " type, or (ii) the valve V2 is used as an additional amplifier for gramophone reproduction.
