Abstract
Time evolution of a signal during a signal epoch is represented by a waveform display in which the foreground pixels in a column of pixels assigned to a time interval within the signal epoch are rendered with a color that depends on frequency-dependent information relating to a time segment that includes the time interval.

An improved method of representing time evolution of a signal during a signal epoch using a rectangular array of pixels in which each column of pixels is assigned to a time interval within the signal epoch, and wherein foreground pixels in a column of pixels form a line segment connecting smaller and greater amplitude values within the time interval to which the column is assigned, wherein the improvement resides in rendering the foreground pixels in a column with a color that depends on frequency-dependent information relating to a time segment that includes the time interval.
An improved method of displaying information regarding a signal of which amplitude and frequency vary with time, in which the signal is used to generate a time domain representation of the amplitude of the signal as a foreground waveform against a background, wherein the improvement resides in varying the color with which the waveform is displayed as a function of frequency-dependent information obtained from the signal.
A computer programmed to process a signal that evolves with time during a signal epoch by:
- (a) partitioning the signal epoch into a plurality of consecutive time segments,
- (b) processing the signal to extract frequency-dependent information that characterizes each time segment,
- (c) assigning a value to each time segment based on the frequency-dependent information that characterizes the time segment,
- (d) receiving a user input to select a time segment of the signal,
- (e) determining whether the value assigned to another time segment matches the value assigned to the user selected time segment, and, if so,
- (f) providing an output which emphasizes at least one such time segment.
A method of navigating a signal record, comprising:
- (a) partitioning the signal record into a plurality of consecutive segments,
- (b) processing the signal record to extract frequency-dependent information that characterizes each time segment,
- (c) assigning a value to each time segment based on the frequency-dependent information that characterizes the time segment,
- (d) selecting a time segment of the signal record,
- (e) determining whether the value assigned to another time segment matches the value assigned to the user selected time segment, and, if so,
- (f) emphasizing at least one such time segment.
