Huy guys....have the following questions from signals and systems....
Determine whether the following signals is periodic...If it is periodic determine its fundamental period....
a) 2cos(9t+pi/6)
b) x(t) = sin^2(tpi/6)
c)x[n] = cos((pi*n^2)/8)
d)x[n] = 5sin((3pi/8)*n) + 3cos((pi/6)*n)
I have attached the file with the questions.....
