The DFT of a signal x(n) of length N is X(k). When X(k) is given and x(n) is computed from it, the length of x(n)
A. Is increased to infinity
B. Remains N
C. Becomes 2N – 1
D. Becomes N2
Answer:A
The DFT of a signal x(n) of length N is X(k). When X(k) is given and x(n) is computed from it, the length of x(n)
A. Is increased to infinity B. Remains N C. Becomes 2N – 1 D. Becomes N2
Explanation: When X (k) is given and x (n) is computed from it, the length of x (n) is increased to infinity.
