Given a real valued function x (t) with period T. Its trigonometric Fourier series expansion contains no term of frequency ω = 2π \(\frac{(2k)}{T}\); where, k = 1, 2….. Also no terms are present. Then, x(t) satisfies the equation ____________ |
A. | x (t) = x (t+T) = -x (t + \(\frac{T}{2}\)) |
B. | x (t) = x (t+T) = x (t + \(\frac{T}{2}\)) |
C. | x (t) = x (t-T) = -x (t – \(\frac{T}{2}\)) |
D. | x (t) = x (t-T) = x (t – \(\frac{T}{2}\)) |
