Abstract :
The problem of error reduction is studied. Both synchronous and asynchronous samplings are considered, and a method is proposed for describing the error in the frequency domain. Its advantages are that the input signal does not need to be restricted to the band-limited hypothesis, and that a comparison of the various processing methods can be conveniently made. A compensation method for improving accuracy is discussed
