In automotive applications, it is often a requirement to observe vibration and noise as a function of the rotational speed of the engine. This paper discusses the combination of a low cost input channel architecture, high speed multiplexing and analog to digital conversion and an accurate tracking mechanism to synchronize the sampling process and the required alias protection with the number of revolutions of the engine. The behavior of the tracking ratio tuner is discussed in static as well as in run-up/run-down applications.
