Fourier Series
2 (a) Find the fourier series for f(t) = at for −L ≤ t ≤ 0 and f(t)
= bt for 0 ≤ t ≤ L.
(b) Consider our fourier series with a = b = 1. What does the fourier series reduce to in this case?
(c) Use the fourier series f(t) with a = b = 1 with L = π as the external input into the underdamped oscillator ¨ y + ˙y/4 + y = f(t).
i. Find the particular solution yp(t) and use the auxiliary approach as outlined in Harmonic Analysis in 2018.
ii. Write down the transfer function |Y| and create a reasonable sketch of |Y| – use your calculus to find out where |Y| peaks.
iii. What kind of amplifier is this? How are the amplitudes of input frequencies near the peak filtered by the system transfer function compared to those far from the peak?
