✓ ASSESSMENT PROBLEMS Objective 1—Be able to calculate the trigonometric form of the Fourier coefficients for a periodic waveform 16.1 Derive the expressions for $a_v$, $a_k$, and $b_k$ for the periodic voltage function shown if $V_m = 9\pi$ V. 16.2 Refer to Assessment Problem 16.1. a) What is the average value of the periodic voltage? b) Compute the numerical values of $a_1 - a_5$ and $b_1 - b_5$. c) If $T = 125.66$ ms, what is the fundamental frequency in radians per second? d) What is the frequency of the third harmonic in hertz? e) Write the Fourier series up to and including the fifth harmonic. Answer: (a) 21.99 V; (b) -5.2 V, 2.6 V, 0 V, -1.3, and 1.04 V; 9 V, 4.5 V, 0 V, 2.25 V, and 1.8 V; (c) 50 rad/s; (d) 23.87 Hz; (e) $v(t) = 21.99 - 5.2 \cos 50t + 9 \sin 50t + 2.6 \cos 100t + 4.5 \sin 100t - 1.3 \cos 200t + 2.25 \sin 200t + 1.04 \cos 250t + 1.8 \sin 250t$ V. Answer: $a_v = 21.99$ V, $a_k = \frac{6}{k} \sin \frac{4k\pi}{3}$ V, $b_k = \frac{6}{k} (1 - \cos \frac{4k\pi}{3})$ V. NOTE: Also try Chapter Problems 16.1-16.3.

MSI'S information related to the loddletown tours collection follows: Segmented Income Statement for MSI's ToddleTown Tours Product Lines Pet Store Grocery Getaway Post Office Total Parade Sales revenue $ 100,000 $ 95,000 $ 29,000 $ 224,000 Variable costs 43,000 39,000 24,000 106,000 Contribution margin $ 57,000 $ 56,000 $ 5,000 $ 118,000 Less: Direct Fixed costs 6,800 6,100 4,700 17,600 Segment margin, $ 50,200 $ 49,900 $ 300 $ 100,400 Less: Common fixed costs* 5,000 4,750 1,450 11,200 Net operating income (loss) $ 45,200 $ 45,150 $ (-1,150) $ 89,200 *Allocated based on total sales revenue. MSI has determined that elimination of the Post Office Polka (POP) program would not impact sales of the other two items. The remaining fixed overhead currently allocated to the POP product would be redistributed to the remaining two products. Required: 1. Calculate the incremental effect on profit if the POP product is eliminated. 2. Should MSI drop the POP product? 3-a. Calculate the incremental effect on profit if the POP product is eliminated. Suppose that $1,000 of the common fixed costs could be avoided if the POP product line were eliminated. 3-b. Should MSI drop the POP product?
