Questions seems simple but most of them are tricky. So, practice questions must be of the same level as GATE examination questions. Brief Theory Each chapter comprises brief theory covering all the topics. It is very explicit and provides a clear understanding of the topics. Marginal Notes Marginal notes are extra source of learning. They emphasize useful concepts, summarized text and some common mistakes that students need to avoid.

These are highlighted in a text screen showing their importance while reading. Table of Summary The whole text is summarized using tables which helps in quick reading. Problem Solving Method a step by step approach for problem solving procedures.

Practice Exercise Practice exercises covers variety of problems from each topic that enhance your confidence level. Practice exercises are divided into two levels on the basis of complexity.

Similarly, z -transforms enables us to analyze The properties of z -transform are similar discrete time signals and systems in the z -domain.

Like, the Laplace transform, it is also classified as bilateral z -transform and unilateral z -transform. The bilateral or two-sided z -transform is used to analyze both causal and non-causal LTI discrete systems, while the unilateral z -transform is defined only for causal signals. This corresponds to a circle in z plane with radius r as shown in figure 6. Therefore we conclude that the range of values of the variable z for which the sum in equation 6.

Thus, z -transform of a sequence is completely specified if both the expression [X z ] and ROC are given to us.

Let X z be the z -transform of sequence x [n] , expressed as a ratio of two polynomials N z and D z. The poles and zeros of X z are shown in pole-zero plot of figure 6. Chapter 6 The Z-Transform Page 6.

These properties can be proved by taking appropriate examples of different DT signals. Property 1: The ROC is a concentric ring in the z -plane centered about the origin. Hence the ROC will consists of concentric rings centered at zero.

Property 2: The ROC cannot contain any poles. ROC is defined as the values of z for which z -transform X z converges. We know that X z will be infinite at pole, and, therefore X z does not converge at poles. Hence the region of convergence does not include any pole. Property 3: Consider a finite duration sequence x [n] shown in figure 6.

If N1 is negative and N2 is positive, then X z will have both positive and negative powers of z. The negative powers of z becomes unbounded infinity if z " 0.

Similarly positive powers of z becomes unbounded infinity if z " 3. Property 4: Consider a right-sided sequence x [n] shown in figure 6. Let, it is bounded by some value Mx , then equation 6. Property 5: Consider a left-sided signal x [n] Here N 2 can be either positive or negative. Let it is bounded by some value Mx , then equation 6.

The ROC of a left-sided sequence is illustrated in figure 6.

Property 6: For any time N 0 , a two-sided sequence can be divided into sum of left-sided and right-sided sequences as shown in figure 6. The z -transform of x [n] converges for the values of z for which the transform of both xR [n] and xL [n] converges.

From property 4, the ROC of a right-sided sequence is a region which is bounded on the inside by a circle and extending outward to infinity i.

From property 5, the ROC of a left sided sequence is bounded on the outside by a circle and extending inward to zero i.

The ROC for the right-sided sequence xR [n], the left- sequence xL [n] and their combination which is a two sided sequence x [n] are shown in figure 6. If the z -transform X z of x [n] is rational, then its ROC is bounded by poles or extends to infinity. Property 8: If the z -transform X z of x [n] is rational and x [n] is a right-sided sequence then the ROC is the region in the z -plane outside the outermost pole i.

ROC is the region outside a circle with a radius greater than the magnitude of largest pole of X z. This property can be be proved by taking property 4 and 7 together.

Now, we have an idea to enhance our content and present two separate books for each subject: one for theory, which contains brief theory, problem solving methods, fundamental concepts, and points-to-remember.

The second book is about problems, including a vast collection of problems with descriptive and step-by-step solutions that can be understood by an average student. Each book in this package is adequate for the purpose of qualifying GATE for an average student. Each book contains brief theory, fundamental concepts, problem solving methodology, summary of formulae, and a solved question bank. Solutions are presented in a descriptive and step-by-step manner, which are easy to understand for all aspirants.
