The reason of channel signal integrity problem in communication system is analyzed. A new method to solve the problem of channel signal integrity using pre-emphasis design on analog shaping filter is proposed. The design of analog shaping filter is designed and designed At the same time, the amplitude compensation and phase equalization are taken into account, and the simulation and test results of the filter are given. The simulation shaping filter is used in the communication system to test the modulated signal, which verifies its signal integrity improvement and passes The performance test of communication system verifies the improvement of the BER of the analog shaping filter through pre-emphasis design.
