Abstract

The system consists of digital signal producing module, low pass filtering module, pseudo random signal producing module and digital signal analysis module. Pseudo random signals and digital signal analysis module are produced by the FPGA. Digital signal analysis module consists of active filter, level conversion module .This system perfectly completed the digital signal extraction synchronous signal. In the signal-to-noise ratio (SNR)-9.54 dB, the system also can regenerate the signal information, and show the eye chart. Through the oscilloscope we can get the signals eye chart and analysis of the digital signal transmission performance.
