Abstract

PURPOSE: To obtain an accurate output voltage which changes from zero to a prescribed value depending on the frequency of an input signal, by converting the input signal into a binary-coded signal and driving pulse generators by the rising and falling of the input signal.
CONSTITUTION: An input signal is converted into a binary-coded logic signal at 11. The logic signal is changed into a signal of 50% in duty factor at 12. The signal is supplied to reference pulse generators 13, 14, which are driven by the rising and falling of the input signal to produce reference pulse voltages of constant pulse width T. The frequency fs of the binary-coded logic signal changes in a range as fs=fcW 2fc. The pulse width T is set as T=1/2fc. The period of overlapping of the outputs of the generators 13, 14 is detected at 15. An output resulting from the detection is passed through an LPF 16 to determine a time-dependent mean value. A frequency converted voltage output is thus obtained.
