Exercise: Compute the DT Fourier series coefficients of the following discrete-time signal:
$ x(n)=\sum_{k=-\infty}^\infty \left( u[n-5k]-u[n-4-5k] \right) $
After you have obtained the coefficients, write the Fourier series of x(t).
Help: If the function above does not look periodic to you, please read this page.
Answer
Can somebody finish the following computation?
$ \begin{align} a_n &= \sum \\ & = ... \end{align} $
