Abstract
This paper introduces the design of a simple digital signal transm ission perform ance analyzer base on FPGA ,which can be used forthe testofdigitalsignaltransm ission perform ance.Two msequences designed in the analyzerbase on FPG A logic elements,w hich produces digitalsignaland pseudo random signalrespectively, what is more, the Manchester coding output is realized.The channel is simulated by a low-pass filter and the pseudo signalgenerator,the synchronization clock signalis extracted through the Phase-Locked Loop built-in FP-G A .NIOS IIprocessorbuilt-in FPG Aused for the mastercontroller of the analyzer,which interface isfriendly.Fi-nally the signals are accessed into oscilloscope before the eye chart can beobserved,which transm ission perfor-mance estimate can berealized.关键词
