Power of a Square pulse

Hi all,
How to calculate the power of a square pulse. (Not the average power, but power during the positive duty cycle). Can I use v²/R where v= v×t during the postive duty cycle. Or is it ok only to use the v²/R where v is the instanteneous voltage during the positve duty cycle. The negative duty cycle has pulse voltage of zero

Thank You

Re: Power of a Square pulse

sebswin,
The instantaneous Power of the square pulse = V^2/R, where V is the voltage. (V^2 x t)/R gives you the Energy in a single pulse. (V x t)^2/R does not yield anything useful.

Power of a Square pulse

if active (positive) duty have V volts and inactive (negetive) duty have 0 volt, then you can use this formulla:
P = (V^2)/R * (DUTY FACTOR)
as you know DutyFactor = High time / (High time + LOW time)
