Electrical engineering Control theory. Basic Electronics and Lab. We feel that we have included enough examples so as to enable the student to understand the material, even in situations where adequate classroom moculation is not available. Introduction to Finite Element Method. Venkata Rao Every effort has been made to see that there are no errors typographical or otherwise in the material presented. Part III consists of a single chapter Ch 7. Note that looking down the columns for the active switching vectors Vthe output voltages vary as a pulsed sinusoid, with each leg offset by degrees of phase angle.

Principles of Programming Languages. More complicated SVM strategies for the unbalanced operation of four-leg three-phase inverters do exist.

These illustrations, we feel are more informative and provide a better feel for the theory than the figures found in the standard textbooks. Heat and Mass Transfer. Feedback Demodulators – ange locked loop.

Numerical Analysis and Computer Programming. In any course of this kind, examples and exercises are a must.

There are variations of SVM that result in different quality and computational requirements. Principles of Communication Prof.

Project and Production Management. Introduction to Problem Solving and Programming. Numerical Methods and Computation. Advanced Materials and Processes. Basic BJT amplifier configuration: One active area of development is in the reduction of total harmonic distortion THD created by the rapid switching inherent to these algorithms.

Skip to main content. FM Generation and Detection. Enzyme Science and Engineering. The mathematical tools developed in part I and the communication principles discussed in part II have been put together to arrive at the noise performance of various modulation techniques.

Advanced Strength of Materials.

Computer Aided Design and Manufacturing. This leads to eight possible switching vectors for the inverter, V 0 through V 7 with six active switching vectors and two zero vectors. Class A large signal amplifiers, second-harmonic distortion? By going through the examples and working out the exercises, we feel that the candidate should be in a comfortable position to appear for competitive examinations such as GATE, UPSC, etc. These will be promptly acknowledged and efforts would be made to incorporate the required corrections.

Generation of FM Signals. Industrial Drives – Power Electronics. A three-phase inverter as shown to the right converts a DC supply, via a series of switches, to three output legs which could be connected to a three-phase motor. Part II also consists of three chapters Ch 4 to 6 and deals with modulation techniques: Help Center Find new research papers in: However, it is still possible that there are a few errors serious or otherwise.

### NPTEL :: Electronics & Communication Engineering – Communication Engineering

In the opinion of the modulatiin, a thorough understanding and ability to manipulate and mosulation this material is very essential for a proper understanding of the principles of communication presented in part II and III. To cite a few of these: The reference vector is then synthesized using a combination of the two adjacent active switching vectors and one or both of the zero vectors.

Transistor as a switch: Though the mathematical tools developed in part I have been used extensively in the development of the theory in part II and part III, detailed explanations have been provided to make the concepts and ideas clearly understandable and results and analyses intuitively meaningful. Probability and Random Processes.
