A new concept of alias-free sampling of continuous-time processesX = { X(t), -infty < t infty }is introduced. The new concept is shown to be distinct from the traditional concept [1]-[3]. various criteria for a given sampling scheme{t_{n}}to be alias-free in the new sense are developed. The relationship of the new definition to the question of estimating the spectral density functionPhi(lambda)of the continuous-time processXfrom its samples{X(t_{t})}is discussed.
