Description : Explain the operation of folding and time delaying
Last Answer : In a signal x(n), replacing the independent variable n' by'-n' results in x(-n). The result of this operation is a folding or a reflection of the signal about the time origin n=0. A signal x(n) may be shifted in time by replacing the ... 2,1,3,4,2} & x(-n)= {2,4,3,1,2} & x(n-2)={2,1,3,4,2} � �
