On modeling the multirate sensor array
P. A. Neenu, S. Santa Kumari, Ravindra Dhuli · 2012
In this paper we derive a model for a sensor. Such a model can form the basis of characterising the multirate sensor array in terms of a nonuniform filter bank structure. The capabilities and limitations of the model are also highlighted. Two approaches for obtaining the modeling error are presented. The model is extended for the case when the sensor sampling rate is a rational factor of the observation signal Nyquist rate. The additional error that results in this scenario is analysed.
