ABSTRACT:
A waveform generator comprises waveform generating means for generating a waveform signal band-limited using a first band limitation characteristic in accordance with the input signal series, memory means for storing in advance a difference signal between a waveform signal band-limited using the first band limitation characteristic for the input signal series and a waveform signal band-limited using a second band limitation characteristic for the input signal series and outputting the difference signal in accordance with the input signal series, adding means for adding a waveform signal from the waveform generating means to a difference signal from the memory means and outputting the signal band-limited using the second band limitation characteristic, and selector switch means for selectively outputting either a waveform signal from the waveform generating means or a waveform signal from the adding means.
