YU De-yong · 2009
In digital transmission system,Nyquest's rate can be obtained and the efficiency of frequency band will achieve the theory limit value by using the first class partial response transmission.On the theoretical,the shape of the first class partial filters is cosine form,and on the physical,it can not be realized by using analog element.By using Sampling Theorem,the paper first deduce the characteristics of the first class partial response shaping filter that can be realized on the physical from the spectrum overlap.
