ABSTRACT:
The output voltage of a power source is converted into a time signal by a circuit comprising a capacitor to which the voltage is applied, an MOS-FET connected across the capacitor and controlling its discharge rate in accordance with the voltage of the power source and a switching circuit which controls the MOS-FET. The time period representing the voltage of the power source is displayed digitally by counting the number of standard pulses occurring during the time period and digitally displaying the pulse count.
