Explanation: sin^2(3π/5)n = (1-cos(6π/5)n)/2 = 1/2-1/2cos(6π/5)n ; period = 6π/(5*2π) = k/N = 3/5 ; N=5 6. Which signal is called as energy signal?
A. Finite energy and zero power
B. Finite energy and non-zero power
C. Infinite energy and zero power
D. Infinite energy and non-zero power
Answer:A
Explanation: sin^2(3π/5)n = (1-cos(6π/5)n)/2 = 1/2-1/2cos(6π/5)n ; period = 6π/(5*2π) = k/N = 3/5 ; N=5 6. Which signal is called as energy signal?
A. Finite energy and zero power B. Finite energy and non-zero power C. Infinite energy and zero power D. Infinite energy and non-zero power
Explanation: A signal is said to be energy signal if it has finite energy and zero average power.
