Can anyone tell me exactly what is a pulse, is it a 'burst' of dc voltage such as 5 Volts, which starts and stops when the user tells it to?

.

pulse
Rise and fall of some quantity (usually voltage) for a period of time.

pulse fall time
Time for a pulse to decrease from 90% of its peak value to 10% of its peak value.

pulse repetition frequency
The number of times per second that a pulse is transmitted. Pulse rate.

pulse repetition time
Time interval between the start of two consecutive pulses.

pulse rise time
Time required for a pulse to increase from 10% of its peak value to 90% of its peak value.

pulse width

Time interval between the leading edge and trailing edge of a pulse at a point where the amplitude is 50% of the peak value.
