Abstract
629,676. Limiters; frequency modulation. ARMSTRONG, E. H. Jan. 11, 1947, No. 997. Convention date, Aug. 2, 1940. [Class 40 (v)] In a limiter for frequency-modulated signals, comprising a screen-grid valve with the screen maintained at a low potential, and in which current excursions in the positive direction are limited by means of a resistance 7 in series with the anode circuit, the time-constant of the grid condenser and resistance 2, 3 is made short in order to minimize the period during which the limiter is blocked by grid current and to reduce changes in input impedance.
