Abstract

PURPOSE: To simply generate an optional waveform with few distortion in accordance with a frequency by storing the waveform to be generated as time information, angle information and angle varying amount information and varying the velocity reading information like these with a counting means and accumulating means. CONSTITUTION: A third counting means 6 is increased at a given time, a readout address is provided to a storage. means 1 to 3, and time information, angle information and angle varying amount information of the waveform are read. Then an inclining angle of the waveform is set with angle information and a first counting means 4, a reading velocity according to the frequency is set with time information and a second counting means 5, and an inclining direction of the waveform is set with varying amount information and the accumlating means 9 and 10. That is, the value of time information is set so as to be large e.g. in a slowly varying waveform, while the value of time information is set so as to be small in a rapidly varying waveform, and angle information is suitably set so as to match that. By this way, the amount of information according to the frequency is set and the waveform with few distortion is generated.
