摘要： A signal converting apparatus for converting voltage into a pulse signal with a corresponding pulse-width comprises a switching circuit for selecting either one of an input voltage to be converted or a constant voltage depending upon a binary switching signal. The selected voltage is integrated with respect to time by an integrating circuit. When the output from the integrating circuit has reached an upper limit voltage or a lower limit voltage, the above-mentioned binary switching signal which is an output signal of this signal converting apparatus is inverted by a comparator/inverter circuit.
