Z-Transforms In the study of discrete-time signal and systems, we have thus far considered the time-domain and the frequency domain. The z-domain gives us a third representation. All three domains are related to each other. A special feature of the z-transform is that for the signals and system of interest to us, all of the analysis will be in. Example of z-transform (1) Find the z-transform for the signal γnun, where γ is a constant. By definition Since un = 1 for all n ≥ 0 (step function), Apply the geometric progression formula: Therefore: L5.1 p496 PYKC 3-Mar-11 E2.5 Signals & Linear Systems Lecture 15 Slide 6 Example of z-transform (2). (Z-Transforms) Objective: To understand the meaning of ROC in Z transforms and the need to consider it. Introduction: As we are aware that the Z- transform of a discrete signal x(n) is given by 𝑋 =𝑧 𝑧− ∞ =−∞ The Z-transform has two parts which are, the expression and Region of Convergence respectively.

Z Transform Equation

Have you ever tried your text to fit along the edge of a circle, or even within a circle? Or, on a curved path, or even as a roller coaster? Mostof the time, you need not play as much with words but sometimes if you want to create a quick logo, or even an easy graphic, then you will findPowerPoint's Transform tools for text very useful. Look at Figure 1 below to explore some quick text effects possible right withinPowerPoint.

Transform is a special stylizing option available in PowerPoint only for text. Follow these steps to explore more inPowerPoint 2010 for Windows:

1. Select the text to which you want to apply Transform texteffect. Alternatively, if you just want to follow this tutorial step-by-step,insert a text box on a blank slide and type some text in it asshown in Figure 2. Select the text, or the entire text box as required to bring up the Drawing Tools Format tab onthe Ribbon as shown highlighted in red withinFigure 2.

Note: The Drawing Tools Format tab is a Contextual tab. Contextual tabs are special tabs in theRibbon that are not visible all the time. They make an appearanceonly when you are working with a particular slide object which can be edited using the options within these tabs.
2. Within the Drawing Tools Format tab, locate the WordArt Styles group. Then click theText Effects button that you can see highlighted in red within Figure 3.

3. This opens the Text Effects drop-down gallery, as shown in Figure 4. Select the Transformoption which is the last option in this gallery (shown highlighted in red within Figure 4).

4. This opens the Transform sub-gallery as shown in Figure 5.

6. Let us explore various effects within Transform sub-gallery as marked in Figure 5:

A. No Transform

7. Removes any transform effect already applied to the selected text.

B. Follow Path

8. These Transform effects make your text to flow in a certain path like a circle, or an arc etc.

C. Warp

9. Here you will find Transform effects that twist and turn your text in various directions, and also make them wavy. To explore moreWarp effects, use the scroll bar towards right (highlighted in blue, within Figure 5).
5. When you hover your cursor over any of the Transform effects within the Transform sub-gallery, you will see aLive Preview of the effect on your selected text. Click on any effect toapply it to the selected text. In Figure 6 you can see the selected text applied with Chevron Up effect.

6. Do you notice the pink handle on the left of the text box in Figure 6, above (highlighted in red)? Youcan use that to create more transforms for text. We explain this option in ourAdvanced Text Transforms in PowerPoint 2010 tutorial.Remember to save your presentation often.
