ABSTRACT:
An independent transmitter/receiver, or a transponder in a communication system, receives signals distorted by outside, unwanted conditions such as noise, line capacitance, and so forth. The status of a switch is checked at periodic times, by pulsing, rather than by continuous current flow, to conserve power. The invention includes a debounce circuit for monitoring the switch status; the debounce circuit is adjusted by a debounce select signal received from outside the transmitter/receiver. In addition a sensing circuit is coupled between the switch being monitored and the debounce circuit. The sensing circuit also has its sensing operation adjusted as a function of the debounce select signal. This allows for accurate monitoring of the switch condition, notwithstanding noise, line capacitance and other factors.
