Consider the random phasor sum of Section 2.9 with the single change that the phases \(\phi_{k}\) are uniformly distributed on \((-\pi / 2, \pi / 2)\). Find the following quantities: \(\bar{r}, \bar{i}, \sigma_{r}^{2}, \sigma_{i}^{2}\), and \(ho\). Make a rough plot of the contours of constant probability density in the complex plane.
