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.
Claims11
A display system for displaying a representation of a plurality of input data signals, said display system comprising:
- a display;
- a pixelization unit to convert each of said plurality of input data signals to a pixel value with pixel color and intensity information
- a pixel address generator coupled to the pixelization unit for generating pixel memory addresses based on information in each pixel value and a pattern representing root pixel addresses for displaying successive data samples on the display;
- a display memory coupled to the display and the pixelization unit for storing pixel intensity values at pixel memory addresses for display on said display;
- and
- a pixel aging unit coupled to the display memory, said pixel aging unit for modifying pixel information in the display memory based on predetermined aging criteria and age information associated with pixel values.
A system for generating display data representative of one or more input data signals for display on a display system comprising:
- a converter coupled to receive and responsive to each of said one or more input data signals, wherein said converter converts each of said one or more input data signals into a pixel value comprising pixel color and intensity information;
- a memory coupled to the converter to store pixel values for display on the display;
- and
- a pixel aging unit coupled to the memory to modify pixel values in the memory based on a predetermined aging criteria and individual age information associated with and maintained for the pixel values.
