Given the price history below, suppose you bought 1 share of Amazon and Microsoft stocks on 1/3/2017 and sold one year later on 1/3/2018. Assuming both stocks do not pay dividends and have no stock splits, what are the simple returns of each stock and which had a higher return for the year?

1. The module passed around in class is a v785 from CAEN. It is a 32 channel, 12-bit adc, with a total voltage range of approximately 4 V. The user adjusts the preamplifier electronics so that a 10 MeV signal is registered at the upper end of the experimental spectrum. Assume the device is perfectly linear. a. What is the voltage r10ange of the least significant bit (LSB)? b. What channel in the spectrum does the centroid of the 6288-keV $^{220}Rn$ alpha appear? c. Assuming no contribution from noise, what resolution is possible for the 6288-keV alpha?

1. The center of gravity of a signal $x[n]$ is defined as \begin{equation} c = \frac{\sum_{n=-\infty}^{\infty} nx[n]}{\sum_{n=-\infty}^{\infty} x[n]} \end{equation} and provides a measure of the time delay of the signal. Find an expression for $c$ in terms of $X(e^{j\omega})$. 2. Consider the case where $x[n]$ is real. The quantity \begin{equation} D = \sum_{n=-\infty}^{\infty} n^2 x^2[n] \end{equation} provides a measure of the effective duration of $x[n]$. Find an expression for $D$ in terms of $X(e^{j\omega})$. 3. If $X(e^{j\omega}) = L(\omega)e^{j\theta(\omega)}$, where $L(\omega)$ and $\theta(\omega)$ are real, show that $D$ is minimized for $\theta(\omega) = 0$ (assuming that $\theta(\omega)$ is the only free parameter).

3. (35pts; including 10 bonus pts) For the system shown below: f k2 b1 k1 WE m G(s) = \frac{X(s)}{F(s)} b2 X (1) (10pts) Find the transfer function G(s) as a function of m, b1, b2, k1, k2. What is the order of this system? (2) (15pts) The system parameters are given as shown below. As the b? value is small, you could model this system without considering the b? value (i.e., set b? = 0). What is the order of the system now? Then, find the settling time ($T_s$) and percent overshoot (%OS) of a step response of this system. m = 1 kg, b? = 0.2 Ns/m, b2 = 1 Ns/m, k? = 1 N/m, k2 = 2 N\cdot s/m (3) (10pts: bonus) Use MATLAB to plot step responses of the two systems (one with the original system, and the other with the approximated system by setting m = 0) in the same figure and check whether the system approximation is valid.
