Question 10 (15 points) Let T be a discrete-time system that maps an input signal $x(n)$ to an output signal $y(n)$ according to $\qquad y(n) = \sum_{k=0}^{2}(-1)^{k}x(n - k)$ Let $H(z)$ be the $z$-transform of the impulse response of $T$. a) Find the zeros of $H(z)$ and plot the zeros on the complex plane. b) Find the magnitude response $|H(\Omega)|$ for $T$. Simplify your answer. c) Find the unwrapped phase response $(arg[H(\Omega)])$ for $T$ over $-\pi \le \Omega \le \pi$. d) Is $T$ best described as a lowpass, highpass, or bandpass system? Explain your answer. e) Is $T$ a linear phase system? Explain your answer. f) Is $T$ a generalized linear phase system? Explain your answer.
