代码说明:
由设计要求可知,wp=0.3π内衰减应大于15dB。为了验证数字滤波器的实际滤波功能,设计程序时,把输入序列定为验证函数x(t)=4sin(100πt)以及x(t)=4sin(200πt)和x(t)=4sin(400πt)。又因为Ts=1.25ms,T=80ms,故采样点为64,即N=64,所以当M=6,可以同时调试并验证程序的滤波功能。(Seen by the design requirements, wp < = 0.2π, allow a margin of error of less than 1dB, ws> = 0.3π within attenuation greater than 15dB. In order to verify the actual filtering function of the digital filter design program, the input sequence as validation function x (t) = 4sin (100πt) and x (t) = 4sin (200πt) and x (t) = 4sin (400πt) . And because Ts = 1.25ms, T = 80ms, so the sampling points is 64, that is N = 64, so when M = 6, can debug and validate filtering program.)
