Periodicity of Shifted Sum
I struggle to understand how to prove whether or not a signal is periodic if the signal is written as the sum of shifted functions. A good example of this type of problem would be problem number 1 from the recent exam:
$ x(t) = \sum_{k=-\infty}^{\infty}\frac{1}{(t+2k)^2 + 1} $
