Features

Proves, and not just states, most of the presented statements.

Reviews signals and systems in Chapter 1.

Ensures that students understand how to make continuous time and discrete time signals and systems coexist (Chapter 2).

Covers the most common approaches to Digital and Analog Filter design (Finite Impulse Response and Infinite Impulse Response) and makes students aware of the theory and limitations behind each technique.

Presents the fundamentals of Multi Rate digital signal processing, with applications to signal resampling, efficient filter design and signal digitization.

Introduces signal decomposition by Filter Banks with particular attention to DFT in Chapter 7 and Maximally Decimated structures in Chapter 8. They both are at the basis of the Time Frequency decomposition presented in the last chapter (Chapter 9), such as the Short Time Fourier Transform and the Gabor Transform (from the DFT Filter Banks), and the Wavelet Transform (from the Maximally Decimated Filter Banks);

Introduces Transmultiplexers with particular attention to applications to digital communications techniques such Time Division and Frequency Division Multiple Access (TDMA and FDMA) and Multi Carrier (MC) modulation, also called Orthogonal Frequency Division Multiplexing (OFDM).
