Guessing a periodic signal based on a few properties given

Properties:

A) Fundamental Period = 2

B) $ a_0 = 0 $

C)


Finding the signal based on the properties

A) From A:

N = 2.

$ x[n] = \sum_{k = 0}^{1} a_k e^{jk\pi n} $

$ a_k = \frac{1}{2} \sum_{n=0}^{1} x[n] e^{-jk\pi n} $


B) From B:

$ a_0 = \frac{1}{2} \sum_{n=0}^{1} x[n] = 0 $

Therefore 0.5x[0] + 0.5x[1] = 0
