| Abstract: | To satisfy acoustics characteristics measurement of seabed sediment, a high precision programmable ultrasonic wave signal generator is designed with AD9850 chip which is based on DDS. The basic principle and features of AD9850 are introduced. The power amplification circuit and hardware interface module of MCU and AD9850 were given. The signals generate by the signal generator was used to measure the acoustic characteristics of the seabed sediment, and the experimental results were analyzed. |
