Z -TRANSFORMS AND DIFFERENCE EQUATIONS

PART –A

1 =A(n+1)+B(n)

Put n=0 we get, 1 =A

Put n=-1 we get, 1 =-B (i.e) B=-1

This is the expansion of binominal theorem.

=(1+z-1)n

12. Find Z[e-tt2].

We know that Z[e-at f (t)]=Z[f(t)]z®zeaT

Z[e-tt 2]=[Z[t2]z®zeT

Introduction

The Z-transform plays a vital role in the field of communication Engineering and control Engineering, especially in digital signal processing. Laplace transform and Fourier transform are the most effective tools in the study of continuous time signals, where as Z –transform is used in discrete time signal analysis. The application of Z – transform in discrete analysis is similar to that of the Laplace transform in continuous systems. Moreover, Z-transform has many properties similar to those of the Laplace transform. But, the main difference is Z-transform operates only on sequences of the discrete integer-valued arguments. This chapter gives concrete ideas about Z-transforms and their properties. The last section applies Z-transforms to the solution of difference equations.
