CLIPPER_STROBE

Combination strobe and clipper built around 741C opamp provides two basic functions. First, strobe input of 5 V can reduce gain of amplifier to nearly zero by shorting output to input. Second, clipping function holds all outputs below predetermined level. When used in integrator, circuit provides constant rate of discharge for integrating capacitor. Clipping is done by four-diode bridge having three extra diodes acting as zener. Strobe function is provided by four-diode bridge alone, with strobing input circuit having single-ended input and differential output All transistors are 2N2219,and all diodes are 1N914.－L .Strahan,op Amρ Control Without Reays,EDN /EEE Magazine,Aug,15,1971,p 41-42.
