I am studying for my exam in signal processing.

  For one of the old exam sets, a discrete impulse response of a filter is given as $h[n]$ \begin{bmatrix} -3&0&-3&0 \end{bmatrix}

With a frequency response H[k]$H[k]$. What is the easiest way of calculating the DC gain from this information? I have tried using a DFT but did not see any usable conclusion.
