WebMay 22, 2024 · We need to assess quantitatively the accuracy of the Fourier series approximation so that we can judge how rapidly the series approaches the signal. When we use a ε K ( t) = ∑ k = K + 1 ∞ a k cos ( 2 π k t T) + ∑ k = K + 1 ∞ b k sin ( 2 π k t T) To find the rms error, we must square this expression and integrate it over a period.
