Design of Waveform Simulator System Based on AD9833 and MSP430
Abstract：Based on MSP430F169 MCU and AD9833 chip,a high accuracy programmable ultrasonic wave signal simulator using DDS(direct digital frequency synthesis) technique is designed.It can produce sine wave,tri-angular wave and pulse,which has 1 Hz-1 MHz frequency range of output waveform.Some modules are designed for the generator,such as power supply circuit,control circuit,waveform simulator circuit,wave filter circuit,amplify circuit and so on.The characteristics of the AD9833 chip is given,the software design methodology is provided including initiative,write control word,synthesis frequency and etc.Finally,the simulation results show the correctness and the affectivity of the proposed method.
