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 appli-

cations 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 prob-

lems 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 fi lters

• IRR (infi nite impulse response) and FIR (fi nite impulse response) fi lters

Misza Kalechman is a professor of electrical and telecommunication engineering technol-

ogy 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 labo-

ratories 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 (offi cers

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 Petroleos de Venezuela (PDVSA) Intevep and various refi neries

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 (Alpi-

Rad-Tronics), and a number of other publications.
