Hey everyone, the question I am faced with is this:
Which of the following expressions involving δ[n] is incorrect?
where "m" is a non zero integer and u[n] is the unit step function.
A. u[n-m] = δ[n] + u[n-m+1]
B. x[n]δ[n-m] = x[n-m]
C. δ[n] = u[n] - u[n-1]
D. δ[n]δ[n-m] = 0
I have been scratching my head for a while, but really not sure what to do. Any help as always would be greatly appreciated!
