Abstract: With AD9833 chip which is based on DDS technique, we design a high accuracy
programmable ultrasonicwave signal simulator. The basic principle and performance character of DDS
technique are discussed, and the experimental results are analyzed.
Key words: DDS technology; AD9833; ultrasonic wave.
