Choice of channels. Find the capacity C of the union of two channels (X1, p1(y1|x1), Y1) and (X2, p2(y2|x2), Y2), where at each time, one can send a symbol over channel 1 or channel 2 but not both. Assume that the output alphabets are distinct and do not intersect. Show that 2C = 2C1 + 2C2 . Thus, 2C is the effective alphabet size of a channel with capacity C.

3. Include appropriate error checking in the function. 4. For the specific case of $\mu_1 = -1$ and $\mu_2 = 1$, plot the estimated probability of decision error $Pr(c)$ versus the standard deviation of AWGN. On the samegraph plot theoretical expression for $Pr(E)$. 5. Plot the probability of decision error $Pr(c)$ when the transmitted symbols are $\mu_1 = 0$ and $\mu_2 = 1$.

The reaction shown below does not give the product indicated. Which of the following best explains the error? 1. $O_3$ 2. Zn, $H_2O^+$ The product should be a dicarboxylic acid. The reaction has the arrow drawn in the wrong direction (reactants and products should switch places). The starting reactant should be a cis-diol The reactant should be a trans-diol The reagent would react with both alkene groups, not just one.
