Abstract:
The conventiona l filtering function in the ECG s igna l processing is realized by ana log filte r. H ow eve r, the ana log filter can no t mee t the g row ing needs in the developing signa l acqu isition system because the analog filter has m any d isadvantages such as the lim ited prec ision and the low speed and so on. This paper presents a new solution for a dig ita l filter in the ECG signa l processing, w hich is based on the MATLAB and IP. The dig ital filter can conquer the d isadvantages of analog filter. The code o f dig ital filter is generated by com bin ingMATLAB w ith IP, and then the programm e o f decod ing and ed iting is down loaded into the FPGA by the so ftware o fQuartusII to rea lize the hardw are and softw are design of the dig ita l filte r. Such am ethod m akes a d ig ita l filter ex traord inarily s imp le and reliable. Furthe rmo re, the d ig ita l filte r is testified tom eet the requests o f ECG instrum ent in practise.
