ABSTRACT:
An input amplifier circuit, specifically, an input amplifier circuit for logic signals, in which noise signal components having a duration less than a predetermined duration are eliminated from the output signal of the amplifier. A delay circuit is added to the feedback loop of a Schmitt trigger amplifier circuit which has a delay time equal to the predetermined delay. The delay circuit effectively inhibits the output signal from changing state unless the input signal has a duration greater than the predetermined duration.
