【Abstract】 The principle of using multiphase filter to realize a channel receiver is discussed,and the features that the negative frequency of complex analytic filter is equal to zero, and impulse response of the filter has 90° phase shift between real part and imaginary part are introduced. Then, the realization of a channel receiver based on complex analytic multiphase filter group is presented. Finally, the designing correctness and feasibility of the receiver is proved by the simulation of AM signal demodulation with Matlab.更多还原
