Electrical Engineering Understanding Digital Transmission and Recording A Volume in the IEEE Press Understanding Science & Technology Series With the advent of PCs, the Internet, high–speed modems, compact discs, and digital (including high–definition digital) television, the analog world is quickly being replaced by the digital world. Digital transmission applications are now a major force in the communications industry. Understanding Digital Transmission and Recording explains the technical fundamentals behind it all. Written expressly for engineers, students, and professionals working across industries, Understanding Digital Transmission and Recording combines a highly pictorial approach with practical mathematics to provide an exceptionally intuitive learning experience for the reader. The author details the two basic, problems in digital transmission and recording: first, how to design digital signals so that the information is transmitted or recorded accurately and efficiently; and second, how to encode essentially analog information such as speech and video into digital form. This book also discusses timely new topics such as the digital versatile disk (DVD), the next–generation compact disc. Readers will gain a practical understanding of:
- Digital modulation and coding schemes commonly used for power limited and bandwidth limited channels
- Multiple–access techniques, such as spread spectrum
- Digitization of voice and video with and without data compression
- Elements of the MPEG2 compression technique used for digital TV
- How the compact disc works, including transmission techniques
- Fourier analysis, needed to understand the digital signaling waveforms
Even the communications engineer who is steeped in the mathematics of the field will find this book helpful in understanding the larger picture.
About the Author
About the Author Irwin Lebow started his career at Massachusetts Institute of Technology (MIT) Lincoln Laboratory, where he participated in the first stirrings of the digital revolution, contributing to pioneering efforts in digital computer design, error correction coding, and satellite communications. He later held senior–level positions in government and industry in Washington, D.C., where he is now a consulting engineer. Dr. Lebow has authored and coauthored three other books in the field of digital communications.
