"*The Gibbs Phenomenon* [image: User-added image] To describe a signal with a discontinuity in the time domain requires infinite frequency content. In practice, it is not possible to sample infinite frequency content. The truncation of frequency content causes a time domain ringing artifact on the signal, which is called the “Gibbs phenomenon”." in order to eliminate the ringing artifact altogether, you'd need a hell of an ADC, one that doesn't exist today (nor shall one ever exist to eliminate the artifact). it is part sampling theory and there's no way around it.
