✦ Synopsis

A finite series expansion method using discrete Legendre orthogonal polynomials

(DLOPs) is applied to analyze linear time-varying discrete systems. An effective algorithm is derived to establish a representation which relates the DLOP coeficient vector of a product function to those of its two-component functions. By using this representation, along with the time-shift operational matrix of DLOP, a linear time-varying diSference equation is converted into a set of linear algebraic equations. It is therefore convenient for computer computation.
