1. Digitize the following systems to find $H_d(z)$ by using the bilinear transformation where $H_d(z) = H\left(\frac{2}{T}\left(\frac{z-1}{z+1}\right)\right)$. Assume that $T = 0.2$ seconds. The answers should have all terms in their simplest integer form over a common denominator. a. $H(s) = \frac{2}{s+2}$ b. $H(s) = \frac{s}{s+4}$ c. $H(s) = \frac{s}{(s^2+4s+4)}$

A guitar with strings of length L = 0.62 m has new strings put on it. The low E string has a linear density of \rho = 0.0052 kg/m and when tuned properly should produce a fundamental tone of \nu = 82.41 Hz. Randomized Variables L = 0.62 m \rho = 0.0052 kg/m Part (a) What is the proper tension the string should be under, in Newtons?
