摘要
本文基于DDS技术设计了一种用于超声相控发射电路的相位波形产生器,发射信号的波形、频率、相位等多项参数具有可调性,并且可以实现很高的相位延时分辨率。应用Altera公司推出的DSP Builder、Model-Sim和QuartusⅡ软件进行了仿真及部分硬件实现。
Based on DDS technology,this paper designs a phasewaveform generator for ultrasound phased launch.Waveform,frequency,phase,and many other parameters of transmitted signal with adjustable,and it can achieve very high resolution of phase delay.Application of Altera Corporation introduces DSP Builder,ModelSim,and QuartusII software.This paper conducts a simulation and some of the hardware implementations.
