Between 1950 and 1965, there was a spate of intense activity to investigate the theory and application of ferrite materials at microwave frequencies, and in the early 1960s a number of textbooks on the microwave applications of ferrites were published, but nothing comprehensive since. Now this book has been written to consolidate all the investigations of ferrites for microwave applications, to look back at earlier publications from the viewpoint of a mature technology, and to bring the story up to date. This book attempts to give all the structures and applications using ferrites at microwave frequencies that havebeen investigated or contemplated, using the engineer's rather than the physicist's approach. It starts with a full mathematical treatment of the interaction of an electromagnetic wave with a gyromagnetic ferrite material for simple boundary conditions. These results are then extended to give a field descriptive approach to describe the mode of operation of all the different microwave devices.

Foundations of Digital Signal Processing: Theory, algorithms and hardware design starts by introducing the mathematical foundations of DSP, assuming little prior knowledge of the subject from the reader, and moves on to discuss more complex topics such as Fourier, Laplace and digital filtering. It provides detailed information on off-line, real-time and DSP programming, and guides the reader through advanced topics such as DSP hardware design, FIR and IIR filter design and difference equation manipulation.
