(Im)pulse signals can have any form: from a Dirac pulse over the Gaussian bell curve, sine-, logarithmic- or exponential-shaped forms up to square (or rectangular) pulses.
So the Gaussian pulse is just a special case of an (im)pulse signal.
Gaussian is just statistic. And by the form some pulses are called gaussian. So you need to tell more precise what you need or why you need to know this, in what contex.
I do not understand what you mean by : PSD.,character,.

Like Erill wrote, a gaussian puls is an pulse, so we need to know what kind of pulse. Now you ask "what is the difference between a Mercedes and a car". There is no, so you need to ask something like, "what is the difference between the number of kW of a Mercedes engine and a BMW engine", they are both cars and you want to compare the power of their engines.
So what is the other impulse ?
