1517948 Limiters SONY CORP 9 Sept 1975 [12 Sept 1974] 37071/75 Heading H4R In a limiter having a signal path 1-2 with a series or shunt impedance Q1 controlled by a current source Q2, Q4, Q5 responsive to a voltage obtained by rectification Q3 of the signal in the path 1-2, a diode D1 forward-connected between the output of the current source and the output of the rectifier Q3 forms part of a bypass selectively operable S1, S2 to prevent (leakage) control current reaching the impedance Ql and thereby causing distortion.
