Optimal Design of Filter for Digital Power Amplifier in Vehicle-ground System
As a key part of digital power amplifier, Class D power amplifier circuit in traditional vehicle-ground communication system is prone to communication errors and signal distortion, which affect the effective transmission of signals between vehicles and ground. In view of the above problems, this design uses the design principle of Butterworth filter, through theoretical calculation and simulation analysis of the filter circuit, determines the optimal scheme of circuit parameters, and achieves the purpose of improving the performance of digital power amplifier. Experiments show that the design scheme can effectively reduce the signal distortion and improve the signal-to-noise ratio. It has high practicability in practical application.
