Q1: Choose the function f(t), - ∞ < t < + ∞, for which a Fourier series cannot be definedA 3 sin (25t)
B 4 cos (20t + 3) + 2 sin (10t)
C exp - | t | sin 25 t
D 1
ANS:C - exp - | t | sin 25 t Fourier series is applicable for periodic or finite duration signal and (c) is neither periodic nor finite duration signal. |
