Abstract

877,040. Non linear circuits. RACAL ENGINEERING Ltd. June 22, 1960 [June 26, 1959], No. 21943/59. Class 40(6) [Also in Group XL(b) ] In a circuit for providing overload protection for a radio receiver a single section Pi-filter network comprises a series arm consisting of two inductors L 1 , L 2 in parallel with a shunt capacitor C 1 , and two diodes D 1 , D 2 are connected back to back across the output of the filter. The value of capacitor C 1 is made approximately equal to the shunt capacitance of the silicon diodes at zero bias. The inductors L 1 , L 2 are wound of resistance wire indicated diagrammatically by resistors R 1 , R 2 .
