The sine/cosine representation of two periodic signals are given below: $\infty$ 4 $x_1(t) = \sum_{n=1} \frac{4}{n\pi} \sin(\frac{n\pi}{2}) \cos(2n\pi t)$ and $\infty$ 4 $x_2(t) = \sum_{n=1}^{n=odd} \frac{4}{n\pi} \cos(2n\pi t)$ i. Discuss the symmetry of the given signals $x_1(t)$ and $x_2(t)$. ii. Convert each signal to its amplitude/phase representation. iii. Using MATLAB plot the magnitude and phase spectra of each signal for the first five non-zero harmonics. iv. Convert each signal to its complex exponential representation. v. Using MATLAB plot the double-sided magnitude and phase spectra of each signal for the first five non-zero harmonics. vi. By comparing the spectra of $x_1(t)$ and $x_2(t)$, identify the relationship between the two signals.
