| Abstract: | The core part of the function wave generator was made up of IC MAX038 chip in this paper. The design of the external circuit was simple and tried. Sine pulse and triangle waveforms could be produced by the function wave generator. 10-4 was achieved in the frequency stability and accuracy. The distortion of sine waveform was about 1%. By using the control chip made up of the C805 IF005 Single Chip Micyoco, the function wave generator could output waveforms selected with keyboard, and show the frequency of outputting signal on LCD. |
