Let the signal

$x(t)=\sum_{k=-\infty }^{+\infty } (-1)^{k} \delta (t-\frac{k}{2000})$

be passed through an LTI system with frequency response $H(\omega )$, as given in the figure below.

The fourier series representation of the output is given as

  1. $4000+4000\cos (2000 \pi t)+4000\cos (4000 \pi t)$
  2. $2000+2000\cos (2000 \pi t)+2000\cos (4000 \pi t)$
  3. $4000\cos (2000 \pi t)$
  4. $2000\cos (2000 \pi t)$
