ABSTRACT:
A method for positioning cursors at a specific point on a displayed waveform uses a cursor to determine the maximum and minimum points on the waveform about a transition portion. For each position of the cursor between the maximum and minimum points an intersection between the cursor and the waveform is computed as a percentage of the difference between the maximum and minimum points. The cursor is then positioned at a point on the transition portion where the percentage is a desired value for the specific point.
