Abstract
The objective of this letter is to obtain minimum order input-output e quations for a class of linear time-varying digital filters in state e quation with constant dimension state vector. It is shown that the min imum order of the input-output equation may not be identical to the di mension of the state vector and there exists a nonunique solution for the minimum order input-output equation.
