Topic: Digital Signal Processing
Consider the discrete time signal x(n) = {1, 1, 1, 1, 0.5, 0.5}. y(n) = conv (δ(n - 1), x(n)) is:
- A. 1
- B. δ(n - 1)
- C. x(n - 1)
- D. 5
Answer: C. x(n - 1)
Explanation: x(n) = {1, 1, 1, 1, 0.5, 0.5}. y(n) = conv(δ(n - 1), x(n)) = x(n - 1) (Using property of impulse function).
