Frequency-domain Analysis of Sampling-and-Interpolation Different Sequence
Yuan Xiao · Communications technology · 2009
In the digital signal processing,it is a common thing to change the digital signal's sampling rate.This paper mainly ananlyzes the influence on digital signal processing from the frequency-domain when sampling and interpolating different sequences.This paper first briefly discusses the system of sampling and interpolation.Then,it focuses on analyzing the sampling and interpolation of different sequences in the frequency-domain.According to sampling and interpolation of different sequences,the loss of signal's baseband bandwidth is analyzed in two situations.By comparing the losses of signal's baseband bandwidth caused by these two situations,an in-depth understanding of the influence on the digital signal processing is acquired when sampling and interpolating different sequences.
