Direct Sampling Theory of Signal
Zhang Er · Journal of National University of Defense Technology · 2002
Classical sampling theorem establishes the relationship between the band_limited signal and its uniform samples This paper reinforces it in three aspects First, the error formula of the reconstructed signal and the original signal is presented when the theorem conditions are not satisfied Second, this paper analyzes the uniform sampling of the band_pass signal using concise method, and then gets the conditions which the sampling frequency should satisfy Last, the nonuniform sampling of the band_pass signal is studied The consent range for sampling frequency and the reconstructed formula from its nonuniform samples are presented All this enriches and deepens the classical sampling theorem
