Abstract : The patent describes a frequency to voltage converter including a switching circuit responsive to an input signal at each zero crossing in the positive direction to charge a capacitor to a peak negative voltage. The capacitor discharges through a resistor towards a positive voltage until the next zero crossing in the positive direction. The peak voltage charge is coupled to a holding circuit to provide a D.C. voltage proportional to the frequency of the input signal.
