Harmonic signal synthesis system design based on STC15 + TLC5620

摘要

Analyze the signal synthesis process on Matlab theory platform, based on the theory STC15W1K24S chip and 4 road 8 digit serial d/a TLC5620 produced by TI Company are designed to be a signal synthesis circuit system. By using the system module we can created the one, three, five, seven time's harmonic component of the signal, those signal components could be compounded to the original signal. The harmonic components and the synthetic wave of any number of times can be observed and analyzed by means of an oscilloscope. The system can realize the synthesis of any four signals, and it is a portable waveform synthesize, which can be used to simply observe and analyses of signal synthesis in laboratory and outdoor.
