(a) For the function $f(x,y,z) = x \cdot \overline{y} \cdot z + x \cdot \overline{y}$: (12 points) Draw the K-Map representation. You only draw the map; you do not need to simplify the function. (b) For the function $f(x, y, z) = \prod M(1,4,5,6)$ Write the function in canonical POS form. Write the function in simplest POS form. (12 points) Calculate the cost of the logic network for part (b). Draw the simplest logic network for part (b) using only NOR devices.

(1) In a drawer there are five brown socks and three green socks. Our experiment is to selected at random two socks and removed in succession from this drawer. (a) List the elements of the sample space (b) List the corresponding probabilities for each element of the sample space (c) List the corresponding values $w$ of the random variable $W$, where $W$ is the number of brown socks selected. Hint: Make a table with three columns and 4 rows. In each row you add an element of the sample space, the probability of that element and the number of brown socks that this realization has. (3) Find the probability distribution and the cumulative distribution function of the random variable of problem 1. Write a table with the values of $f(x)$ and $F(x)$ for all possible $x$'s you have and make a chart for the probability distribution and another for the cumulative distribution function. Hint: Re-write the same table you did for problem 1, but this time add two more columns, one to account for $f(x)$ and another to account for $F(x)$.

Problem 1: Understanding the derivation of the diode IV characteristics (adapted from a problem in Pierret) (Objective 4: Understand the physics and models of semiconductor devices including diodes.) Consider a one-sided pn-junction diode with $N_a \gg N_d$. This will allow us to focus our analysis on electrons injected from the n-type side to the p-type side. This problem asks you to repeat the derivation on slides 19-30 in Lecture 9 (sections 4.7-4.9 in Hu) for a simplified case. (a) Write down the steady state continuity equation that applies to excess electrons, $n'$, in the p-type neutral region. (b) We do not have an electric field in the neutral region, so we do not need to worry about drift. Simplify the equation from (a) by eliminating the drift term and substituting $L_N = \sqrt{D_N \tau_N}$. (c) Write down the general solution to the differential equation in (b). (d) Write down the boundary conditions for $n'$ at the depletion edge ($x_p$) and as $x \to \infty$. These are the same boundary conditions used in class and on the slides. (e) Find unknown coefficients in part (c) using the boundary conditions in part (d). (f) Find the electron diffusion current density for electrons on the p-type side. (g) How does your answer for (f) compare to the normal equation for the diode current density? ($J = qn_i^2 \left(\frac{D_p}{L_p N_d} + \frac{D_N}{L_N N_a}\right) \left(e^{\frac{qV}{kT}} - 1\right)$) Hint: it should be the same as if one let approximated the full equation based on the assumption that $N_a \gg N_d$.
