Last year Packages had sales of $325,000 and a net income of $19,000, and its year-end assets were $250,000. The firm's total-debt-to-total-assets ratio was 45.0%. a. Based on the DuPont equation, what was the ROE? (Hint: use the firm's debt ratio to solve for total debt. Once you have total debt, you can calculate owner's equity. Owner's equity is required to solve for the equity multiplier of the firm.) b. Suppose the firm reduces its equity multiplier (EM) by 10%, what effect will it have on ROE? Do you think the firm took the right action by reducing equity multiplier? Explain in detail the effects of reducing EM on ROE, and under what circumstances such actions are beneficial for the firm and how?

A LTI digital filter is characterized with output coefficient vector ak = [0.5, 0.25] and input coefficient vector b = [10.75]. Q1: Write out the Linear Difference Equation that describes this LTI Digital Filter. (10 marks) Q2: Write out the Linear Difference Equation using the z-operator. (10 marks) Q3: From Q1 or Q2 above or otherwise, write out the System Function H(z) for this Digital Filter, where H(z) = Y(z)/X(z) and Y(z) and X(z) are y(n) and x(n) respectively in the z-operator domain. (10 marks) Q4: How would you use Matlab to plot the Pole-Zero Diagram of this digital filter? (5 marks) Q5: How would you use Matlab to plot the 1-sided magnitude and phase frequency responses of this digital filter? (5 marks) Q6: Make a sketch of the two-sided Magnitude Frequency Specification of a Bandpass Filter that has a sampling frequency of 16 kHz, stopband cutoff frequencies of 3 kHz and 7 kHz, and passband cutoff frequencies of 4 kHz and 6 kHz. (10 marks) Q7: Convert the frequency axis in Q6 to (i) Discrete Frequency Axis and (ii) Normalized Frequency Axis. (10 marks) Q8: A DSP system comprises three digital filters with respective impulse responses h1[n], h2[n], and h3[n] that are connected in series cascade. Given h1[n] = [1, 0, 1], h2[n] = [1, -1], and h3[n] = [1, 2, 1], use linear convolution to compute the overall equivalent impulse response h[n] of the DSP system. (20 marks) Q9: Given h4[n] = [1, 2, 1] and h5[n] = [2, 4, 2] that are to be used as separable filters in a 2D convolution algorithm, compute (i) the 3x3 vertical kernel and (ii) the 3x3 horizontal kernel that can be used in denoising a 2D image using 2D convolution. (10 marks) Q10: Given a clean signal x[n] of length 1024 that is contaminated with a noise component w[n] of length 1024, write down (in detail) how you compute the Signal-to-Noise Ratio (SNR) in dBs?
