After all, in a step response, the input signal is a square wave composed of an infinite series of sine waves. The filter will truncate the infinite series of sine waves. Any sufficiently truncated series of sine waves will show Gibbs ringing. http://math.arizona.edu/~friedlan/teach/456/gibbs.pdf second opinion werkgever
