If it is, find its inverse system and use a block diagram to represent the inverse system. ] [ ] [ ∑ −∞ = = n k k x n y 6. Show that a system having the superposition property must satisfy a) the additivity condition; and (Hint: Choose suitable values for a and b .) b) the scaling condition. (Hint: Use the same approach as in part (a).) 7. Is it always true that the power of the sum of two signals x 1 (t) + x 2 (t) equals the sum of the power of x 1 (t) and the power of x 2 (t)?
