ABSTRACT:
An arrangement for the dynamic direct display of pulses in the nanosecond range operates without oscilloscopes or other special display apparatus. To display pulse timing or amplitude characteristics, a pulse sequence is applied to an equidistant tapped delay line, the output from each tap being connected to a bistable storage element with an indicator lamp in the output. A plurality of indicator lamps are arranged in the form of a matrix. If a pulse occurs on a tap during a sampling interval, the associated indicator lamp is turned on. The sequence and identity of the turned on indicators is indicative of the pulse spacing and the pulse width in the pulse sequence.
