用matlab设计一个抽取率为2的CIC抽取滤波器和插值率为2的插值滤波器,Using matlab to design a decimation rate of 2 of the CIC decimation filter and interpolation rate of 2 of the interpolation filter

clc clear number of subbands K = 32 oversampling ratio O = 2 decimation rate D = K/O number of taps per polyphase component P = 3 total prototype filter length is L = D*P prototype filter-clc clear number of
