Modern Electronic CommunicationUpplaga 8

Now in its eighth edition,Modern Electronic Communicationthoroughly examines the key concepts in electronic communications. The book contains many examples of communication circuit troubleshooting and includes extensive use of Electronics Workbench Multisim throughout. This edition has expanded the coverage of digital communications to present readers with the latest techniques and methods which reflect current practices in industry. “Troubleshooting with Electronics Workbench Multisim” sections at the end of each chapter help readers gain the understanding of an important concept presented in the chapter by presenting circuits in a tutorial manner.This edition still features the best of older communication circuits with new content on current circuits, data sheets, and communication techniques from Philips Semiconductor, Maxim, Analog Devices, Lectrosonics, and Zarlink. Updated wireless digital communications topics include direct sequence spread spectrum (DSSS), spreading and de-spreading the signal, pseudo noise (PN) codes, Orthogonal Frequency Division Multiplexing (OFDM), phase-shift keying (PSK), and frequency shift keying, troubleshooting cellular telephone problems.A thorough and up-to-date reference for Electronic Technicians.
