ABSTRACT:
A first frequency-to-voltage converter responds to an input pulse signal and outputs a first signal, whose peaks are at a level varying according to the period of the input signal, and whose troughs are at a substantially constant level. A second frequency-to-voltage converter responds to the input signal and outputs a second signal, whose troughs are at a level varying according to the period of the input signal. A discriminating means then determines a frequency decrease in the input signal past a predetermined frequency by sensing a peak in the first signal above a first level and determines a frequency increase in the input signal past the predetermined frequency by sensing a trough in the second signal below a second level.
