Abstract: Digital samples of signal data are displayed on a display system in patterns that are selected for display. Stored patterns are designed to allow a rapid visual determination of whether the signal's characteristics match a previously determined signal characteristic, and if not, provide for diagnosis of the signal variation by the observer. Multiple signal channels can be simultaneously displayed in patterns to allow observation and measurement of the relationships between multiple signals. Signal data values are allowed to be displayed as pixels whose color and intensity represent specific data characteristics, and those color and intensity values can vary as a function of time as a part of the specific pattern designed for each signal type.
