Abstract:
A large real-time processing of ultrasonic signals is a very important part in the ultrasound diagnosis system,especially with digital hardware processing.A key part of the signal processing is the filter design which will affect the performance of ultrasound diagnostic equipment.In this paper,the classification of digital filters is introduced briefly,and a number of hardware implementation methods of digital filter in recent years,especially the realization of FIR filters which belongs to the classical filter based on Distributed Algorithms are discussed.Then a number of advantages and problems of digital filter in recent years are analyzed.On this basis,the paper forecasts its developing trends in the future.
