Answer:A
Explanation: T1=2π/2π/7 = 7 , T2=2π/3π/5=5/3 , T1/T2=5/21 , T=21T1 or 5T2 , T=35 5. Find the fundamental period of 1+sin^2 (3π/5)n .
A. 10/3 B. 5 C. 3π/5 D. None of the mentioned
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?
