Compute $ E\infty $
$ E\infty=\int_{-\infty}^\infty |4|^2\,dt=16t|_{-\infty}^\infty $
$ E\infty=\infty $
Compute $ P\infty $
$ P\infty=lim_{T \to \infty} \ \frac{1}{(2T)}\int|4|^2dt $
$ P\infty=lim_{T \to \infty} \ \frac{1}{(2T)}*16|_{-T}^T $
$ P\infty=lim_{T \to \infty} \ \frac{1}{(2T)}*16(T-(-T)) $
$ P\infty=lim_{T \to \infty} \ 16 $
$ P\infty=16 $
