0 0 votes Two analog signals $x_{1}(t)$ and $x_{2}(t)(t$ in second $)$, are sampled at a rate $F_{s}=40 \mathrm{~Hz}$, where\[x_{1}(t)=\cos (20 \pi t), t \geq 0, \text { and } x_{2}(t)=\cos (100 \pi t), t \geq 0\]The first ten samples (starting from $t=0$ ) are considered for the analysis.Which of the following statements is TRUE?All of the first three samples of $x_{1}(t)$ are greater than the corresponding samples of $x_{2}(t)$.All of the last three samples of $x_{1}(t)$ are greater than the corresponding samples of $x_{2}(t)$.All of the samples of $x_{2}(t)$ are greater than the corresponding samples of $x_{1}(t)$.All of the fourth to seventh samples of $x_{1}(t)$ are equal to the corresponding samples of $x_{2}(t)$.
