    help ...to control pulse width of a -15vdc pulse train

    Firstly, thank you Kevin and hero for taking the time.... Kevin",If the load is a high impedance FET, then it can be done more easily. If the load is low impedance, you should change the circuit which generates the pulse". Yes, it does have a high impedance fet- the fet is the main driver for...

    help ...to control pulse width of a -15vdc pulse train

    Thanks for the reply, The pulse train (20 kHz negative pulses with respect to gnd) remain constant in frequency period is 50 micro-secs' The width is automatically adjusted between 6 and 20 usec by the current PWM..Which is (completely epoxy bonded) so no change can be made at that level. 1...

    help ...to control pulse width of a -15vdc pulse train

    Help needed to control the pulse width of a (negative) -15vdc pulse train at 20khz.. Basically, the pulse is as described in the picture attached which is of the pulse itself all details are within picture. Pulse width is 6 micro-sec, and i want to be able to reduce increase or reduce it by...
