The z-transform is useful for the manipulation of discrete data sequences and has useful for verifying the z-transform expression X (z) using MATLAB. Note that since MATLAB is a numerical processor (unless the Symbolic toolbox is used), it cannot be used for direct z-transform calculations. We will now elaborate on this. Z - Transform 1 CEN543, Dr. Ghulam Muhammad King Saud University The z-transform is a very important tool in describing and analyzing digital systems. It offers the techniques for digital filter design and frequency analysis of digital signals. ¦ f f n X ( ) x[n]z n Definition of z-transform: For causal sequence, x(n) = 0, n< 0:
Example 12.3. 2. We will begin by letting x [ n] = f [ n − η]. Now let's take the z-transform with the previous expression substituted in for x [ n]. X ( z) = ∑ n = − ∞ ∞ f [ n − η] z − n. Now let's make a simple change of variables, where σ = n − η. Through the calculations below, you can see that only the variable in the

5.2 Fundamental Properties of z-Transform and Examples z-Transform tables are very similar to those of Laplace and DTFT transforms and it has several important properties just like them. The critical ones have been tabulated in Table 5.1. TABLE 5.1 PROPERTIES OF z-TRANSFORM 1. Linearity A.x 1 [n] + B.x 2 [n] A.X 1 (z) + B.X 2 (z) x[n + N] −

These properties are helpful in computing transforms of complex time-domain discrete signals. 1. Linearity: If we have two sequences x 1 [n] and x 2 [n], and their individual z-transforms as X 1 (z) and X 2 (z), then the linearity property permits us to write: This is easily proved. First consider. 2. The Z Transform, the DTFT, and Digital Filters INTRODUCTION The Z transform pairs that one encounters when solving difference equations involve discrete-time signals, which are The MATLAB tool 'freqz' is very handy, but we will use 'plotZTP.m' to gain the same information, and more! (NB: The 'plotZTP.m' requires two other
Solving Dierential Equations with Laplace Transform The Laplace transform provides a particularly powerful method of solving dierential equations — it transforms a dierential equation into an algebraic equation. Method (where Lrepresents the Laplace transform): dierential algebraic algebraic dierential equation −→ ↓solve −→
