Solve problems 2.30 and 2.31 in the textbook with addition of the following terms (5 Cos 18.84t + 4 Cos 56.5t) to e(t), using the Fast Fourier Transform algorithm via Matlab. Hint for Matlab: For plotting the amplitude spectrum, instead of plot (f,A), use stem(f,A) to create the plot of the frequency vector f versus the amplitude vector A.

2.30 2.31 2.32 e. The note produced by a guitar string. f. AM and FM radio signals. 2s.s IA 0- Represent the function miog odi e(t) = 5 sin 31.4t + 2 sin 44t elt\ = 5 Cos 18.84€ + 4 Cos 56.5t as a discrete set of N = 128 numbers separated by a time increment of (1/N). Use an appropriate algo- rithm to construct an amplitude spectrum from this data set. (Hint: A spreadsheet program or the pro- gram file DataSpect will handle this task.) Repeat Problem 2.30 using a data set of 256 num- bers at 8t = (1/N) and St= (1/2N) seconds. Com- pare and discuss the results. A particular strain sensor is mounted to an aircraft wing that is subjected to periodic wind gusts. The 2 strain measurement system indicates a periodic
