Abstract
Method and system for estimating an eye diagram display of a real signal passing through a data communication channel, according to which decoded symbols of the transmitted real signal are captured, along with their corresponding ADC sample values and sampled at a rate of 1 SPS or more. Then statistic data is collected for each captured sequence of bits/symbols for each particular phase and a synthetic signal is created, based on the collected statistics, using a signal generator that produces samples by randomly creating a bit stream by generating a corresponding one or more samples for any symbol sequences in the bit stream according to the number of collected phases. Interpolation on the corresponding samples is then performed, according to required display time resolution and the synthetic signal is then displayed as a two-dimensional eye diagram image, representing all the statistics collected at all phases.
