TRACE LOCATOR FOR A MULTI-TRACE RECORDER

摘要

APPLICATION OF PAUL A. DIDDENS TRACE LOCATOR FOR A MULTI-TRACE RECORDER 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 is displayed without a movement of the recording medium to enable the 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.
