A SIGNAL GENERATOR OF SINE AND COSINE WAVES WITH ACCURATE PHASE RELATIONSHIP |
| |
| Abstract: | This paper discussed a signal generator of sine and cosine wave which is composed of the digital circuits, it can generate the sine and cosine waves with the same frequency and accurate phase relationship. The frequency of the output signals can be adjusted separately, the distortion is lowered, and the stability raised. |
