Even … WebJan 6, 2024 · I have to calculate the Fourier coefficients of this signal. I found that signal equation is. y = A ( 2 t − T) T. To find Fourier coefficients I wrote. x k = 2 A T ∫ 0 T / 2 2 t − T T e − i 2 π k f 0 ′ t. In this case. f 0 ′ = f 0. because the period is T_0. I calculate the integration by parts of the first integral and I obtained.
