This paper presents an introduction to the important topic of sensor signal validation where multiply-redundant measurements of critical variables are available. Pertinent results from a collection of previous publications have been reviewed in this paper, but it does not serve as a survey of the field of signal validation. The intention is to focus on redundancy management in fault detection and isolation with the emphasis on the parity space, which apparently has not been dealt with in details in any other survey or tutorial paper.
