## Abstract

Publisher Summary This chapter discusses z-transform and its two formsâ€”bilateral and unilateral z-transforms. The z-transform converts a numerical sequence x[n] into a function of the complex variable z and it takes two different forms. The bilateral or two-sided z-transform, denoted in this chapter by Zb {x[n]}, is used mainly in signal and image processing, while the unilateral or one-sided z-transform, denoted by Zu {x[n]}, is used mainly in the analysis of discrete time systems and the solution of linear difference equations.
