    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?

    Please Help

    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
