Consisting of eleven chapters, the book has a comprehensive and systematic exposition on the basic theory and method of signal and system analysis.
It utilizes a systems approach to solving practical engineering problems, rather than using the framework of traditional circuit theory. Numerous examples from circuit theory appear throughout, however, to illustrate the various systems techniques introduced. The Fourth Edition has been thoroughly updated to effectively integrate the use of computers and to accurately reflect the latest theoretical advances. The author represents the physical appreciation of concepts rather than the mere mathematical manipulation of symbols in this worldwide version of the first edition, Principles of Signal Processing and Linear Systems.
Instead of viewing engineering as a branch of applied mathematics, the literature employs mathematics to improve physical and intuitive knowledge of topics, rather than to prove an axiomatic theory. Theoretical results are backed up by well chosen examples and analogies whenever possible, allowing students to naturally discover meaning for themselves.
This text presents a comprehensive treatment of signal processing and linear systems suitable for students of electrical engineering. Here, the Laplace transform follows Fourier, rather than the reverse; continuous-time and discrete-time systems are treated sequentially, rather than interwoven. Additionally, the text contains enough material in discrete-time systems to be used not only for a traditional course in signals and systems but also for an introductory course in digital signal processing.
The text provides a balanced and integrated treatment of continuous-time and discrete-time forms of signals and systems intended to reflect their roles in engineering practice. This approach has the pedagogical advantage of helping the reader see the fundamental similarities and differences between discrete-time and continuous-time representations.
It includes a discussion of filtering, modulation and feedback by building on the fundamentals of signals and systems covered in earlier chapters of the book. Polarization Chapter 6. Download second edition Digital Communications Fundamentals and Applications book pdf.

The zero-input response yzi [n] is given by inverse z -transform of Yzi z.
Zero-State Response or Forced Response The zero-state response yzs [n] is the response of the system due to input signal and with zero initial conditions. The zero-state response is obtained from the difference equation 6. The zero-state response yzs [n] is given by inverse z -transform of Yzs z. Total Response The total response y [n] is the response of the system due to input signal and initial output.
The total response can be obtained in following two ways : By taking z -transform of equation 6. The total response y [n] is given by inverse Laplace transform of Y s.
Alternatively, that total response y [n] is given by sum of zero-input response yzi [n] and zero-state response yzs [n]. It is the z -transform of the impulse response. Alternatively we can say that the inverse z -transform of transfer function is the impulse response of the system. In this section, we derive a z -domain condition to check the stability and causality of a system directly from its z -transfer function. The ROC of such a system H z is the exterior of a circle. If H z is rational then the system is said to be causal if A The ROC is the exterior of a circle outside the outermost pole ; and B The degree of the numerator polynomial of H z should be less than or equal to the degree of the denominator polynomial.
Thus, for the system to be causal and stable theses two conditions are satisfied if all the poles are within the unit circle in the z -plane. An LTI discrete time system with the rational system function H z is said to be both causal and stable if all the poles of H z lies inside the unit circle.
Now consider the different ROCs. ROC : 0. Hence A is correct option. So inverse system is not stable and causal. Basic elements of block diagram with their z -domain representation is shown in table 6. This structure is called direct form-I structure. This structure uses separate delay elements for both input and output of the system. So, this realization uses more memory. Now put these values in general structure of Direct form-I realization we get 6.
It uses less number of delay elements then the Direct Form I structure. Substitute these values in general structure of Direct form II , we get 6. Each of these transfer functions is realized in direct form-I or direct form II realization and then they are cascaded. Then the individual transfer functions are realized in direct form I or direct form II realization and connected in parallel for the realization of H z. If x [n] is the input and y [n] is the output to this system, then which of the following difference equation describes the system?
The system is causal and BIBO stable. The system is causal but BIBO unstable. The system is non-causal and BIBO unstable. C causal and stable if all the poles of H z lie inside unit circle. D none of above MCQ 6.
