FIR

  一个1MHz的FIR低通滤波器。 ① 时钟信号频率16MHz; ② 输入信号位宽8bits，符号速率16MHz； ③ 要求在Matlab软件中进行FIR滤波器浮点和定点仿真，并确定FIR滤波器抽头系数； ④ 写出测试仿真程序。(A 1MHz FIR low pass filter. (1) The clock signal frequency is 16MHz; (2) The input signal has a bit width of 8 bits and a symbol rate of 16 MHz; (3) Floating-point and fixed-point simulation of FIR filter is required in Matlab software, and tap coefficients of FIR filter are determined. (4) Write the test simulation program.)
