If a function f( x) has a discontinuity at the The overshoot does not die out as N increases, but instead approaches a finite limit. The Nth partial sum of the Fourier series has large oscillations near the jump, which increases/decreases the maximum/minimum of the partial sum of the function itself. Mathematically, it reflects the difference between uniform convergence and pointwise convergence. Overshoot/undershoot (or "ringing") occurringĪt discontinuities of finite length. So finite Fourier sums (as well as other eigenfunction series) provide an Near every point of discontinuity in an amount proportional to the finite jump. Series of a piecewise continuously differentiable periodicįunction behaves at a jump of discontinuity. Phenomenon is the peculiar manner in which Where the Fourier coefficients ? k and b k were defined previously.
