it's like this i think u wrote that there
or it's don't know if u wrote there for t goes from -11 to 2 or its for t goes from 1 to 2
Step function is defined : for , and for
but when u need to make let's say square signal with amplitude 1 from 0 to 1 u'll do it like this... u put step function and then add one more but negative one that begins at 1 so it looks like this :
and for Laplace , just put it in integral and solve it it's quite simple do u know how it's done ?
Laplace transform (bilateral):
unilateral, just goes from not from ....
P.S. if needed i can write u detailed explanation
here are few signals with step functions, hope it will help u understand how to present signals by using step functions
to see signals bigger just click on them
and here u are a few basic Laplace transformations
well that's not all of "basic" but if u need more.. just say
