Practical MATLAB Applications for Engineers

Practical MATLAB® Applications for Engineers introduces the reader to the concepts of MATLAB® tools used in the solution of advanced engineering course work followed by engineering and technology students. Every chapter of this book discusses the course material used to illustrate the direct connection between the theory and real-world applications encountered in the typical engineering and technology programs at most colleges.

Every chapter has a section, titled Background, in which the basic concepts are introduced and a section in which those concepts are tested, with the objective of exploring a number of worked-out examples that demonstrate and illustrate various classes of real-world problems and its solutions.

The topics include:

• Continuous and discrete signals
• Sampling
• Communication signals
• DC (direct current) analysis
• Transient analysis
• AC (alternating current) analysis
• Fourier series
• Fourier transform
• Spectra analysis
• Frequency response
• Discrete Fourier transform
• Z-transform
• Standard filters
• IRR (infinite impulse response) and FIR (finite impulse response) filters

Author

Misza Kalechman is a professor of electrical and telecommunication engineering technology at New York City College of Technology, part of the City University of New York. Mr. Kalechman graduated from the Academy of Aeronautics (New York), Polytechnic University (BSEE), Columbia University (MSEE), and Universidad Central de Venezuela (UCV; electrical engineering).

Mr. Kalechman was associated with a number of South American universities where he taught undergraduate and graduate courses in electrical, industrial, telecommunication, and computer engineering; and was involved with applied research projects, design of laboratories for diverse systems, and installations of equipment.

He is one of the founders of the Polytechnic of Caracas (Ministry of Higher Education, Venezuela), where he taught and served as its fi rst chair of the Department of System Engineering. He also taught at New York Institute of Technology (NYIT); Escofa (officers telecommunication school of the Venezuelan armed forces); and at the following South American universities: Universidad Central de Venezuela, Universidad Metropolitana, Universidad Catolica Andres Bello, Universidad the Los Andes, and Colegio Universitario
de Cabimas.

He has also worked as a full-time senior project engineer (telecom/computers) at the research oil laboratories at Petroleosde Venezuela (PDVSA) Intevep and various refineries for many years, where he was involved in major projects. He also served as a consultant and project engineer for a number of private industries and government agencies.

Mr. Kalechman is a licensed professional engineer of the State of New York and has written Practical MATLAB for Beginners (Pearson), Laboratorio de Ingenieria Electrica (Alpirad-Tronics), and a number of other publications.
