| Abstract: | This paper presents the partial fundamental theory of the Fourier transform for the staggered perodic sequence. The time-varying property of staggered periodic FIR filter, the maximum system instantaneous response, and the relation amony the output sequence spectrum, the input sequence spectrum and the frequency response of filters are emphatically described. |
