Abstract

PURPOSE: To realize the combination of worst conditions in a shirt time by setting a part or the whole of waveform determining elements to plural conditions independently and changing the combination of conditions by input pulses.
CONSTITUTION: An input pulse is branched and inputted, and digit outputs 21, 22 and 23 are inputted to corresponding terminals of unit 2 as a phase control signal, a pulse width control signal and an amplitude control signal respectively. Digit outputs 21, 22 and 23 become the maximum or minimum condition of control signals for phase, pulse width and amplitude which are waveform determining elements, and the combination of two conditions is changed by the input pulse, so that eight combination of worst conditions can be obtained as the whole and repeated automacically in a short time.
