Abstract
In this communication, we revisit and discuss the relationships among the truncation, discretization, phase, and amplitude dispersion errors of a finite-difference scheme. We show with a simple example how the truncation-error analysis plays a critical role in understanding the numerical inaccuracies not revealed by numerical-dispersion analyses.
