Challenge Problems
Push your limits with challenges.
Question 1
Consider two periodic signals, x1(t) = cos(t) and x2(t) = sin(t). Calculate the Fourier coefficients for the composite signal y(t) = 2cos(t) + 3sin(t).
💡 Hint: Break down the Fourier series coefficients for each component.
Question 2
Using the results from the previous problem, describe how you would analyze the frequency response of a system inputting y(t).
💡 Hint: Remember to consider each harmonic's contribution separately.
