Abstract
An analog to digital converter used along with a variable resistive sensing means utilizes the capabilities of a microprocessor to charge and discharge a capacitor. The time required for this capacitor to discharge is dependent upon the value of the variable resistive sensing means. Circuitry is used to create a pulse whose pulse width is equal to the discharged time of a capacitor through the variable resistive sensing means.
