Exercise 2: Fourier Series Any periodic continuous-time signals can be written as a Fourier series which is the summation of harmonically related complex exponentials. One example is a square wave shown below \frac{1}{2} 0 1 -\frac{1}{2} 1 t It can be written as $\infty$ $x(t) = \sum_{k=1 \atop k \text{ odd}}^{\infty} \frac{2}{\pi k} \sin(2\pi kt)$ Write a MATLAB program to observe how the Fourier series approaches a square wave as the number of terms $k$ increases. Do some self-study on how to produce a movie clip to visualize the convergence of the Fourier series to a square wave.

5. In the experiment carried out to determine the dependence of vapor pressure of pure ethanol on temperature, vapor pressure ethanol was measured at different temperatures (18, 26, 33,40°C and 48°C). A plot of InP versus 1/T was obtained by using the data. The plot yielded a straight line, as given in the figure below. Calculate the enthalpy of vaporization of ethanol by using the slope of the straight line. InP 5.40 4.08 3.10 x10?³ 3.36 x 10?³ 1/T
