EFFECT OF FILTER ON TRIANGLE WAVE To illustrate the effect of the filter on a non-sinusoidal waveform, set the input signal to be a 1 kHz triangular waveform. According to Fourier theory, the triangular waveform at 1 kHz is equal to a summation of sinusoids of frequencies 1 kHz, 3 kHz, 5 kHz, etc. The formula for a triangular waveform is as follows: $$v(t) = \frac{8}{\pi^2} \left[ \sin(2\pi 1000 t) - \frac{1}{3^2} \sin(2\pi 3000 t) + \frac{1}{5^2} \sin(2\pi 5000 t) - ... \right]$$ (1) According to the principle of superposition, the output of the filter will be the summation of the response of the filter to each of the sinusoids in (1). The output amplitude will be the input amplitude times the frequency response for that frequency. Since our filter is designed to eliminate the 1 kHz signal and pass the 3 kHz signal, we would expect that the output signal would look more like the 3 kHz signal. (Note that the 5 kHz signal is small going into the filter and, as the filter frequency response curve shows, the response of the filter makes the small signal even smaller. If possible capture the filter input and output waveforms using an oscilloscope and plot them in Matlab®. Otherwise, sketch the input and output waveform of the filter circuit as shown on the oscilloscope. Comment on whether it appears that the 1 kHz signal is eliminated.

• Write the following Python functions with a variable-length arguments list • Do NOT use Python built-in functions such as max(), sum(), etc. 1. maxVal - returns the largest of arguments (at least one argument needed) • print(maxVal(2)) print(maxVal(2, 1)) print(maxVal(2, 1, 9)) 2. average - returns the average of arguments. If no arguments, return 0. • print(average()) print(average(9)) print(average(1, 2, 3)) print(average(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)) 3. sumOfEvenNum - returns the sum of even numbers of arguments (at least one argument needed) • print(sumOfEvenNum(1, 2, 3)) print(sumOfEvenNum(1, 2, 3, 4, 5, 6, 7, 8, 9, 10))
