ABSTRACT:
Provided is a an overlaid digital signal waveform display for a logic analyzer. The present invention allows the logic analyzer user to overlay, that is superimpose, individual digital waveforms within a functional group of waveforms onto each other so that all the waveform transitions within the group appear at one level across the display screen of the logic analyzer. Thus, all waveforms within a functional group, such as all the address line waveforms of an address bus, can be overlaid onto each other. In addition, individual waveforms within the group can be shown isolated from the overlaid group.
