By original design, a system outputs a 10-volt pulse that is 3 seconds in duration. It is desired to upgrade the square-pulse output with a "soft-start" pulse that steps up to 10 volts in 1-volt increments spaced every 20 milliseconds. Determine the signal duration T so that the "soft-start" pulse has the same signal energy as the original square pulse.
