when we have x(-t) and we time shift it say x(-t-2) it shifts toward the -ve t axis.. where as x(t-2) the function is shifted on the + axis..why is it so??
see when we say there are 2 functions x(t) and x(t-2) it means x(t-2) is delayed by 2 sec with respect to x(t) therefore it shifts in the positive x direction.. does'n't the same apply for x(-t) and x(-t-2) the second function is time delayed by 2 secs wid respect to the first so even it should shift to the positive x axis..isn't it?
