摘要： A bandpass filter includes a plurality of parallel paths. Each path includes a first mixer, a low-pass filter, and a second mixer. The first mixer in each path receives the input signal and mixes the input signal with a periodic mixer sequence. The low-pass filter in each path is operable to filter an output of the associated first mixer. The second mixer in each path is coupled to receive an output of the associated low-pass filter and mixes said filter output with a periodic mixer sequence having a period that is divided into a plurality of time slots, wherein again the mixer value is constant during each time slot. A summer sums the outputs of the second mixers of each of the paths to generate an output of the bandpass filter.
