Abstract

본 발명은 참조파(Reference Wave) 발생장치에 관한 것으로, 특히 롬(Read Only Memory:ROM)에 데이타를 저장하였다가 이를 다시 읽어 들여 참조파를 발생하는 장치에서 참조파 발생을 위한 데이타를 차값만을 저장하여 참조파 발생이 가능 하도록 하여 롬의 크기를 줄이고 파형의 분해능을 상승시키도록 한 참조파 발생장치에 관한 것이다. 이러한 본 발명은 이전 어드레스에 해당하는 데이타 누적값과 현재 어드레스까지의 데이타 누적값과의 차이값을 저장하고 어드레스 발생기에서 얻어지는 어드레스에 해당하는 데이타를 출력시킴과 동시에 데이타의 증감을 나타내는 신호를 출력하는 롬과, 롬에서 출력되는 증감 신호에 따라 이전 데이타와 현재 롬에서 출력되는 데이타를 계산하고 그 결과 데이타를 출력하는 데이타 계산수단과, 데이타 계산수단에서 출력되는 데이타로 참조파의 크기를 조절하고 참조파의 파형을 발생시키는 데이타 처리수단을 구비한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reference wave generator, and more particularly, to store a data in a read only memory (ROM) and read it again to generate a reference wave. The present invention relates to a reference wave generator for storing reference to generate a reference wave, thereby reducing the size of the ROM and increasing the resolution of the waveform. The present invention stores a difference value between the data accumulation value corresponding to the previous address and the data accumulation value up to the current address, outputs data corresponding to the address obtained from the address generator, and outputs a signal indicating the increase or decrease of the data. Data calculation means for calculating previous data and data output from the current ROM according to the ROM and the increase / decrease signal output from the ROM, and outputting the result data, and adjusts the reference wave size with the data output from the data calculation means. And data processing means for generating wave waveforms.
