基于GC5016的超声回波信号解调及动态滤波设计

Design of Demodulation and Dynamic Filter for Ultrasound Echo Signal Based on GC5016

采用了一种用数字上/下变频器GC5016实现超声回波信号的解调和动态滤波处理的方法.使用通常用于调制和解调的芯片GC5016,将超声回波信号的动态滤波处理在信号解调的同时完成,降低了对FPGA乘法器资源的占用.

A method is designed to demodulate and filter the ultrasound echo signals,based on the digital up/down converter GC5016.The signal processing of dynamical filtering is implemented together with the demodulation by GC5016,which is usually used for modulation and demodulation.It decreases the usage of multiplier resources in FPGA.
