ABSTRACT:
In a signal control apparatus for controlling an apparatus input signal to produce an apparatus output signal, a signal producing circuit (11) produces a reference signal in accordance with a plurality of original waveform signals generated by first and second generating circuits (31, 32). The reference signal is compared by a comparing circuit (13) with an output waveform signal which is produced by a detecting circuit (12) dependent on the apparatus output signal. The comparing circuit produces a difference signal representative of a difference between the reference signal and the output waveform signal. Under control of the difference signal, an amplifier (14) processes the apparatus input signal into the apparatus output signal.
