ABSTRACT:
A programmable timer controls the duration of integration with respect to time of an unknown analog signal in accordance with a programmable time period established by a microprocessor. A switching logic successively transfers an analog signal and a voltage reference signal to an integrator under logic control actuated by the programmable timer. A comparator monitors the value of the integration of the reference voltage in order to control the time-out results of an event counter initiated simultaneously with input to the integrator of the reference voltage, for providing a digital count output signal to the microprocessor.
