Circuit to eliminate signal chatter in the output of a fiber-optic receiver

摘要: A signal processing circuit that is subject to chatter provided with chatter-elimination circuitry. Prior circuitry included a peak voltage detector which received data input and representation of the threshold-comparator threshold-comparison first output magnitude when was below predefined threshold second above voltage. Improved elimination achieved by further incorporation differential operational amplifier has (a) terminal receives data-representative chatter, (b) coupled receive either fixed level blocks signal, or variable allows be amplifier, (c) source temperature compensated, threshold-level switch comparison wherein constructed supply
