Abstract
본 발명은 서어보 회로의 예를 들어 리잘리나 자이로와 같은 센서에 필요로 되는 레퍼런스신호를 발생시키는 회로에 관한 것으로. 종래 기술에 의한 레퍼 런스신호 발생장치는 저 항과 캐괘시터등으로 구현하게 되는 발진회로로 되어 이에 따라 온도에 따라 특성 이 변화하므로써 주파수가 온도에 따라 변화하게 되 고 동기 신호를 발생시키지 못하는 문제가 발생되는 바, 본 발명에 의한 레퍼 런스신호 발생장치는 중앙처 리장치 (CPU)에 의해 제어되고 도실 레이터의 클럭신호에 응답하여 소정의 원하는 주파수를 출력하는 소젓의 정현파 발생회로를 구비하고 상기 정현파 발생회로의 출력신모률 소정의 레퍼런스신호』_사용하게 하도록, 상기 중앙터리장치 (CPU)에 연결되고 상기 오실레이터의 출력신호에 응답하여 소정의 신호를 출력하는 카운터회로로서의 타이머와 상기 칵운턴초조에서 출력되는 신호에 응답하여 소정의 원하는 주파수를 출력하는 변환회로로서의 저역통과필터로 구성하므로서, 출력되는 주파수가 디지탈신호를 기본으로 하여 온도변화등와 같은 외부변화에 영향받지 않고 안정된 주파수를 얻게 되고 또한 디지탈신호를 기 본클럭으로 사용하므로 동기 신호의 발생이 용이하고 또한 원하는 주파수를 타이머의 세팅으로 얻을 수 있기 때문에 다른 장치들과 호환성이 있게 되며 동시에 여러가지 주파수를 간단하게 얻을 수 있게 된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit for generating a reference signal required for a sensor such as a rizoli or gyro of a servo circuit. The reference signal generator according to the prior art is an oscillation circuit implemented with a resistor and a causal seat, and thus the characteristics change according to the temperature, so that the frequency changes according to the temperature and the synchronization signal cannot be generated. The reference signal generating device according to the present invention includes a sinusoidal wave generating circuit of a salted fish which is controlled by a central processing unit (CPU) and outputs a predetermined desired frequency in response to the clock signal of the dosulator. The output elongation rate of the generation circuit is referred to as a counter signal which is connected to the central battery unit (CPU) and outputs a predetermined signal in response to the output signal of the oscillator. Low pass filter as a conversion circuit for outputting a predetermined desired frequency in response to the output signal As a result, the output frequency is based on the digital signal and the stable frequency is obtained without being influenced by external changes such as temperature change. Also, the digital signal is used as the basic clock. It is possible to obtain a setting of, which makes it compatible with other devices and at the same time makes it easy to obtain various frequencies.
