$6\mathrm{.}1-2$ Peternine the Nyquits sampling rate and the Nyquist sampling interval for the following sine $(2100$m$).$

$6\mathrm{.}1-3$ A signel $g(f)$ bend$-$limited to $BHz$ is sampled by a periodic pulse train $p{T}_1(t)$ made up a rectangular pulse of width $\frac{1}{88}$ second $($centered at the origin$)$ repeating at the Nyquis $7(28$ pulses per second$).$ Show that the sampled signal $\frac{?}{\text{b}\text{a}\text{r}}(g)(t)$ is given by

$(t)=\frac{1}{4}g(t)+{\displaystyle \underset{n=1}{\overset{}{}}}\frac{2}{n}sin(\frac{n}{4})g(t)cos4nBt$
