ABSTRACT:
A trace locator for identifying in a visual display the position on a recording medium of a recorded trace representing an input signal in a multi-trace recorder. The trace position may be displayed without a movement of the recording medium to enable the possible trace to be located and positioned by observing the visual display. The visual display is sequentially advanced by successive clock signals until a predetermined amplitude of an input signal to be displayed is reached. The trace location is displayed for a preset period of time after which the display is cleared prior to a subsequent display of the trace location for either the same input signal or another input signal.
