ABSTRACT:
A signal converter includes a frequency-to-voltage converter for converting a frequency of an input signal received via an input terminal into a control voltage. The input signal contains a noise signal having a frequency different from the frequency of the input signal. The control voltage changes in accordance with a change of the frequency of the input signal. A filter has a variable cutoff frequency so that the noise signal is eliminated from the input signal and outputs a filtered signal. The variable cutoff frequency is changed in accordance with a change of the control voltage so that a change of the variable cutoff frequency follows a change of the frequency of the input signal. A comparator compares the filtered signal with a reference voltage and converts the filtered signal into a pulse signal having a pulse width corresponding to the frequency of the input signal.
