1. What is a positive externality? What is a negative externality? Why are both of these considered market failure? (12 points) (Your answer should be around 5 sentences and it is up to you if you would like to include graphs, though they are NOT required.) 2. Drew has $20 per week to spend on any combination of slices of blueberry pie and popsicles. The price of a slice of blueberry pie is $4 and the price of a popscile is $2.

1. Find the Fourier transform of the following functions: (a) x(t) = cos(\omega_0t)u(t) 1 (b) x(t) = \frac{1}{0.25+t^2} (c) x(t) = e^tu(-t) 2. Find the inverse Fourier transform of the following functions: 1 (a) X(\omega) = \frac{1}{(0.5+j\omega)^2} j\omega (b) X(\omega) = \frac{j\omega}{(0.5+j\omega)^2} 1 (c) X(\omega) = \sum_{k=-1} \delta(\omega - k\pi/4) 3. An ideal -90^\circ phase shifter is defined by the frequency response: H(\omega) = \begin{cases} e^{-j\pi/2} & \omega > 0\\ e^{+j\pi/2} & \omega < 0 \end{cases} Determine the corresponding impulse response h(t). 4. Consider an ideal low-pass filter with frequency response H(\omega) = \begin{cases} 1 & |\omega| < \omega_c\\ 0 & |\omega| > \omega_c \end{cases} If the input to this filter is x(t) = e^{-2t}u(t), determine the value of \omega_c such that this filter passes exactly one-half of the energy of x(t).
