Abstract

1,185,167. Radio receiving circuits. R. H. MARCO. 8 Nov., 1968 [4 Oct., 1968], No. 47292/68. Addition to 1,185,166. Heading H3Q. In a radio receiver in which, as in the parent Specification, a stage from which automatic gain control is derived is followed by an attenuator and a buffer amplifier feeding the signal detector, the output of a beat oscillator is also applied to the detector.
