说明：  随机共振微弱信号检测龙格库塔方式对信号进行滤波。其中信号为正弦信号(Weak signal detection of stochastic resonance)

定义一个抽象类的CShape,包括纯虚数Area(用来计算面积）和SetData（用来重设形状大小）。然后派生出三角形CTriangle类、矩形CRect类、圆CCircle类，分别求其面积。最后定义一个CArea类，计算这几个形状的面积之和，各形状的数据通过CArea类构造函数或成员函数来设置。-Defines an abstract class CShape, including the pure imaginary number Area (used to calculate the area) and SetData (used to reset the shape, size). Then the triangle CTriangle derived class, rectangle CRect class, round CCircle categories, seeking its size. The final definition of a CArea class, calculate the size of the sum of several shapes, each shape data through CArea class constructor or member function to set up.

说明：  针对已知多频率正弦信号的频谱，设计相应的FIR滤波器(凯塞窗函数法设计低通,高通，带通滤波器，分别提取信号并绘制频域和时域曲线)按要求进行滤波。 根据已知滤波器的性能指标设计IIR数字滤波器(双线性变换法设计巴特沃斯低通IIR数字滤波器)，并对心电图信号进行滤波处理；(For known more frequency sinusoidal signal spectrum, to design the corresponding FIR filter (Kaiser window function method of designing low-pass, high-pass, band-pass filter, respectively, to extract the signal curve) and draw the frequency domain and time domain filtering according to the known filter in accordance with requirements of performance index design of IIR digital filter (bilinear transformation method to design butterworth low-pass IIR digital filter), and to filter the ecg signal)
