Patent Searching and Data


Title:
WAVEFORM GENERATOR
Document Type and Number:
Japanese Patent JPS63231611
Kind Code:
A
Abstract:

PURPOSE: To increase the number of degrees of freedom by outputting address data of waveform data to be read out from each pattern memory to the pattern memory and converting waveform data read out in parallel to serial waveform data and subjecting it to D/A conversion and performing the control in accordance with a preliminarily set sequence program.

CONSTITUTION: A first waveform generating system A is formed with a sequencer 16, an address generating part 10, a pattern memory 8, a data converting part 12, a data selecting part 14, and a D/A converter 15. A second waveform generating system B is formed with the sequencer 16, an address generating part 11, a pattern memory 9, a data converting part 13, the data selecting part 14, and the D/A converter 15. Thus, a waveform is quickly is obtained through relatively inexpensive memories are used, and a waveform generator where the number of degrees of freedom of the sequence program is large is obtained.
