Chebyshev1IIRdigitalfilter

代码说明：

   这是本人夏季学期的课程设计：模拟信号数字化滤波处理的计算仿真-Chebyshev I型低通滤波，对模拟信号进行数字化滤波处理。根据数字滤波器的性能指标，计算出Chebyshev1型低通IIR数字滤波器的系统函数，画出数字滤波器的频率响应曲线，给出Chebyshev1型低通IIR数字滤波器的设计结果。(This is my summer semester of the curriculum design: analog signal processing digital simulation filtering-Chebyshev I-type low-pass filtering, on the analog signal to digital filter processing. Digital filter in accordance with performance indicators, calculated Chebyshev1-type low-pass IIR digital filter systems function, to draw the digital filter frequency response curve, give Chebyshev1 type low-pass IIR digital filter design.)
