Description : Explain the operation of time advancing.
Last Answer : A signal x(n) may be shifted in time by replacing the independent variable ‘n’ by n-k, where k is an integer. If ‘k’ is a negative integer, the time shift results in an advance of the signal by k units in time. x(n)= {2,1,3,4,2} & x(n+2)={2,1,3,4,2}
