ABSTRACT:
Provided is a waveform generating apparatus that generates a signal having an arbitrary waveform, comprising a waveform memory that stores a plurality of pieces of waveform data that each include a sequence of signal values; a filtering section that (i) reads from the waveform memory a piece of waveform data serving as a basis for a waveform to be generated, from among the plurality of pieces of waveform data, (ii) performs a conversion by filtering the read piece of waveform data to obtain a piece of converted waveform data, and (iii) writes to the waveform memory the piece of converted waveform data; and a waveform output section that reads the piece of converted waveform data from the waveform memory and outputs a signal having a waveform corresponding to the sequence of signal values of the read piece of converted waveform data.
