In a recent paper, Hammond demonstrated a use of the evolutionary power spectral density, which was originally introduced by Priestley, for slowly varying random processes appearing in engineering applications. The purpose herein is to show that the form of input-output relationships derived by Hammond under certain assumed asymptotic forms of the responses is also valid without such restrictions, and that it can be derived in a much more straightforward fashion.
