Apparatus for rejecting false edges of an input signal.

摘要

A circuit is utilized to reject false edges from a digital input signal to be provided to a digital circuit from a transmission line. The circuit includes circuitry for sensing the rising and falling edges of the signal and programmably filtering those edges such that the proper signal is transmitted to the digital circuit. The circuit also can be utilized at a plurality of power supply voltage ranges to remove such false edges without appreciably affecting the performance thereof.
