CAD of Digital Filter in High-speed Calling
摘要
Abstract
Firstly,this paper gives the concept of radiant power to adjacentchannel, then derives the original function of 10 order Bessel analog filter, transformates it to digital filter by Euler approximation for transformation of an analog filter to a digital filter, processes separately 2 level and 4 level paging coded signals by the aid of computer, gives the way of design for hardware and the flow chart of program. This method can efficiently lower the radiant power to adjacent channel and reduce adjacent channel interferences,when applied to practical system.关键词
