Telecommunication Circuits and Technology

Telecommunication Circuits and Technology provides students with a problem solving approach to understanding the fundamentals of telecommunications. The author covers the common telecommunication and data communication circuits that are currently taught at further and higher education level and also used in industry. Understanding is reinforced with frequent worked examples and problems for specific applications and industrial data sheets are also given. This text is essential reading for HND/C and degree studnets of electronic or telecommunications engineering. Due to its practical bias, it is also a useful text for technical professionals wishing to update their skills or learn new technology.
