ABSTRACT:
A circuit for continuously monitoring or determining the magnitude of a resistance, capacitance, inductance, voltage or current over a very large dynamic range by means of a signal-to-pulse-train converter, rather than by conventional linear amplification techniques. The circuit in part, comprises a resistance, current or voltage source, and a reactive element. The reactive element is discharged from the power source to operate a temperature insensitive trigger circuit that, in turn, actuates a semiconductor switch recharging the reactive element. The frequency or period of operation is a preselected function of the variable parameter to be determined, as of a transducer.
