It can be seen that theyappear to have about the same pulse width and shape. This is partlydue to the fact that the video amplifier bandwidth is not c^uite adequateto show the actual shape, since in both cases the pulses are slightlyshorter than can be correctly reproduced through this amplifier. Theripples on the base line following the pulses are also due to the videoamplifier characteristics when used with such short pulses. 4.
