A signal composed of sinusoidal signals is given by the equation: $x(t) = 3 \cos (50\pi t - \pi/8) - 5 \cos (150\pi t + \pi/6)$ a. Is $x(t)$ periodic? If so, what is the fundamental period $T_{0,x}$? Which harmonics are present? b. Now consider a new signal: $y(t) = x(t) + 7 \cos (160\pi t - \pi/3)$. How is the spectrum changed? Is $y(t)$ periodic? If so, what is the fundamental period $T_{0,y}$? c. Finally, consider another new signal $w(t) = x(t) + \cos (5\sqrt{2}\pi t + \pi/3)$. How is the spectrum changed? Is $w(t)$ periodic? If so, what is the fundamental period $T_{0,w}$? If not, why not?

EX7-1 Express the following phasor in the polar representation assuming that $V_1$ is a real positive number. $\frac{1}{1 + j\omega CR}V_1$ Hint With real numbers $r$ and $\phi$, put $re^{j\phi} = \frac{1}{1 + j\omega CR}V_1$. You are to find $r$ and $\phi$. Define $\theta$ with $\tan \theta = \omega CR$ and express $r$ and $\phi$ by using $\theta$ and $V_1$.
