Question 1
What does the DC component represent in both forms of Fourier Series?
💡 Hint: Consider the value when plotted over time.
Question 2
In the exponential Fourier series, how is c_k for positive harmonics (k > 0) derived from trigonometric coefficients?
- c_k = a_k + b_k
- c_k = (1/2)(a_k - j b_k)
- c_k = (a_k / 2) + (j b_k / 2)
💡 Hint: Which equation combines both components into one?
