Abstract
A signal converter includes a generator for generating first and second clock signals having recurrence periods equal to each other and phases different from each other, an input for receiving as a signal to be converted a signal which has signal levels not lower than a predetermined level during an arbitrary period of time, a counter for counting the first clock signals from the generator in a period of time corresponding to the signal period of time, and an output arrangement. The output arrangement provides for delivering either of two signals in dependence on which of time intervals determined by the first and second clock signals an end of said signal period of time lies in, whereby signals of the counter and the output arrangement are used as a converted signal.
