Gemma and her husband Evan decided to separate in May, 2023, but filed no paperwork with any court. They do not wish to file a joint return for 2023. They have two children Abigail (3) and Thomas (8) who lived with both parents until the separation and then with Gemma, except for twice-a-month weekend visits with their dad after Evan moved out on October 1, 2023. What filing status will Gemma use on her 2023 tax return?

6. [worth 30 points total] Consider a system which has two zeros at $z = 0$ and two poles at $ae^{\pm j\omega_0}$, $0 < a < 1$. Such a system is known as a digital resonator. The system function is therefore (the $b_0$ term is simply a scaling constant): $H(z) = \frac{b_0}{(1 - ae^{j\omega_0}z^{-1})(1 - ae^{-j\omega_0}z^{-1})} = \frac{b_0}{1 - (2a \cos \omega_0)z^{-1} + a^2z^{-2}}$ The DTFT of a digital resonator is therefore: $H(\omega) = \frac{b_0}{1 - (2a \cos \omega_0)e^{-j\omega} + a^2e^{-2j\omega}}$ Now, assume that we choose the normalization factor as follows (this ensures that $|H(\omega_0)| = 1)$: $b_0 = (1 - a)\sqrt{1 + a^2 - 2a \cos (2\omega_0)}$. (a) Plot the pole zero locations corresponding to $H(z)$ for $a = 0.95$ and $a = 0.7$. For both values of $a$, assume $\omega_0 = \pi/3$. (10 points) (b) Open a $2 \times 1$ figure window and plot the magnitude and phase spectra of $H(\omega)$ for $a = 0.95$ and $a = 0.7$. That is, on one plot, superimpose the magnitude spectra for the two values of $a$. Similarly, on the other plot, superimpose the phase spectra for the two values of $a$. For both values of $a$, assume $\omega_0 = \pi/3$. Judging by the magnitude spectra, do you see why this system is called a resonator? (10 points)
