ABSTRACT:
Automatic extraction of pulse parametrics from multi-valued functions, such as a digital serial communications signal, is achieved by building up an eye pattern data array from multiple acquisitions of the multi-valued functions. One axis of the data array represents amplitude and another represents time, and the contents of each element of the array represents the number of times a data point occurs within the amplitude-time interval represented by the element during the multiple acquisitions. After the data array has been built, histograms representing summations of selected elements of the data array are obtained. From the histogram information the pulse parametrics are determined, such as amplitude levels for the various states of the signal as well as the characteristics of transition paths between states.
