Noise theory is continuing to gain momentum as a leading topic. Developments in the field are proving increasingly important to the electronics engineer or researcher specialising in communications and microwave engineering. This text provides a comprehensive overview of noise theory in linear and nonlinear circuits and serves as a practical guide for engineers designing circuits where noise is a significant factor. Features include:

• A practical approach to the design of noise circuits

• Graphical representations of noise quantities

• Definition of all noise quantities for both active and passive circuits

• Formulae for the conversion of different sets of noise parameters

• Equations derived for the overall noise parameters of embedded noisy networks

• Determination of Volterra transfer functions of nonlinear multi-port networks containing multi-dimensional nonlinearities

• Analysis of noise theory in nonlinear networks based on the multi-port Volterra-series approach

Presenting material currently only available in the primary literature, this book serves as an invaluable reference source for advanced students, academics and researchers in the fields of electronics and microwave engineering. The comprehensive coverage will also appeal to communications and microwave engineers in industry.
