1. The problem statement, all variables and given/known data
If x2[t]= x1[t-2]
and x3[t]=x2[2t]
What is x3[t] in terms of x1[t]?
a) x3[t]= x1[2(t-2)]
b) x3[t]= x1[2t-2]
2. Relevant equations
which one?
3. The attempt at a solution
offcourse, but I am struggling with this concept of shifting. But I believe the answer should be A. since x3[t] is the compression version of x2[t], which is the shift version of x1[t].
So the overall transformation would be x3[2(t-2)], which is not correct.
