ABSTRACT:
A waveform synthesizing circuit comprises a plurality of signal output switching means for outputting predetermined magnitudes of voltage or current signals when a voltage or current value of an input pulse reaches preliminarily assigned comparing reference values, a signal summing means for superimposing output signals from a plurality of signal output switching means for summing, and a comparing signal switching means detecting the rising and falling of the input pulse, providing the comparing reference values with given differences between a plurality of signal output switching means according to an order of operation of a plurality of signal output switching means upon the detection of a rise, and providing the comparing reference values, which are different from those for rising, with given differences between a plurality of signal output switching means according to an order of operation of a plurality of signal output switching means upon the detection of a fall.
