Abstract
802,055. Frequency modulation. GENERAL ELECTRIC CO., Ltd. July 16, 1956, No. 21998/56. Class 40 (5). A detector circuit selectively adapted for angle or amplitude modulated carrier waves comprises a known F.M. ratio detector 21 the output of which, developed between condensers 13 and resistors 16 and 17, is applied to a lowpass filter comprising resistor 22 and condensers 23 and 24. When ganged switches 19, 25 and 26, connected for F.M. reception as shown in the Figure are operated, they form a known amplitude modulation detector comprising rectifier 10, half of winding 8, winding 14, resistors 15 and 16, load resistor 22 and by-pass condenser 23.
