| 摘 要： | 研制了以FPGA为核心的数字幅频均衡器,在较宽的频带内校正了因传输系统不理想引起的信号幅度及相位失真。系统使用带阻滤波网络模拟信号的传输系统,利用Filter Solutions软件合理设定网络中元器件的参数,并得出其幅频特性。依据该特性,推导出与之匹配的均衡器参数,结合MATLAB软件的仿真分析结果,在FPGA中调用实现FIR滤波算法的IP核,对失真信号进行均衡处理。该均衡器具有实时性强、采样率高、动态范围大、稳定性高、通用性好等优点,可以实现对传输系统的理想均衡。

| Abstract: | A new kind of digital equalizer is designed in this paper,which works with FPGA as core device.This system revises the signal's amplitude and phase distortion caused by the no ideal of the transmission system in a wide bandwidth.A band-stop filter network is adopted in the system to simulate signal's transmission system.Choosing reasonable parameters for each component in the network with the application of software called Filter Solutions,and then work out its amplitude-frequency characteristic.Figure out ... |
