Abstract:
Signal transmission modal was established by using scattering parameter method for the radiated noise of high speed digital circuit. Mechanism of radiated noise generated by signal ringing wave was analyzed. Furthermore,PCB electromagnetic parameters were extracted by employing CST software,and the equivalent circuit was presented. Signal transmission was improved after matching the characteristic impedance of PCB. Theory analysis and experiment results show that signal ( basic frequency was 480 MHz) in USB cable of HD visual aids was improved. Radiated noise was decreased 12 dBμV/m and can meet GB 9254.
