Slide wire device simulator circuit and method

摘要

A circuit for simulating a slide wire device includes a pair of resistors connected electrically in series with a reference voltage source. Switching means are provided for alternately shorting the resistors in a duty cycle fashion such that when one of the resistors is shorted, the other resistor is unshorted. By adjusting this duty cycle, the output provided by the circuit is adjusted and a slide wire device simulated.
