n this article, an application of a new data processing tool-wavelet transform is introduced. It can be used forrnscience study in physiology and the other subjects. Here we offer a method of extracting respiration frequency and heart beat ratefrom blood pressure waveform curve with wavelet transform and FFT.%本文提供了一种新的数字信号处理工具—小波变换和小波分析程序流程图，可用于生理及其它学科科研实验研究。文中给出了利用Gauss—阶导数小波变换从家兔动脉血压信号中提取呼吸频率及心率的方法。
