Understanding Digital Signal Processing, Second Edition is simply the best way for students to master DSP technology. Richard G. Lyons has thoroughly updated and expanded his best-selling first edition, building on the exceptionally readable coverage that has made it a favorite of both students and professionals worldwide. Lyons achieves the perfect balance between practice and mathematics, making DSP accessible to beginners without ever oversimplifying it, and offering systematic practical guidance for day-to-day problem-solving. Down-to-earth, intuitive, and example-rich, this book helps readers thoroughly grasp the basics and quickly move on to more sophisticated techniques. Coverage includes: discrete sequences/systems, DFT, FFT, finite/infinite impulse response filters, discrete Hilbert transforms, sample rate conversion, signal averaging, and much more. This edition adds extensive new coverage of quadrature signals, complete with easy-to-understand 3D drawings. It also contains extended discussions of IIR and FIR digital filtering, and new coverage of cascaded integrator-comb and interpolated FIR filters. Lyons has also provided more than twice as many DSP tips and tricks as in the first edition—including techniques even seasoned professionals may have overlooked.
