| Abstract: | The hardware structure of the signal generator was presented and the working principle of AD9833 chip (DDS)was expounded,including the SPI communication process and the software implementation of sine signals,triangle signals and square wave signals.Verifying the performance of waveform generator on the con-trol platform established shows that,this signal generator has less high-frequency noise in signals output and higher frequency accuracy. |
