Abstract

802,809. Frequency modulation; automatic gain control. PYE, Ltd. Nov. 4, 1955 [Nov. 10, 1954], No. 32518/54. Drawings to Specification. Class 40 (5). In a frequency modulation receiver having a limiter deriving at its control grid a voltage used for automatic gain control the time constant of the A.G.C. filter circuit is made small compared with the rise time of interference pulses so that the voltage across it can follow the pulse interference and mainly suppress it.
