| Abstract: | Square-root raised cosine roll off digital filter was widely applied to shaping filter and in digital communication system. This paper first discuss the basic principle of shaping filter design, then analyze the performance effect of the main parameters on shaping filter. At last, a designing method and steps from frequency domain is given for square-root raised cosine roll-off digital filter. |
