<b>This book covers the fundamentals of digital signal processing (DSP) in a concise format accessible to anyone with a technical background enabling the reader for further DSP training research and development.<b> <p>The authors explore many subjects including discrete time (digital) signals and systems with emphasis on linear shift invariant (LSI) systems; Fourier and the z transforms; signal sampling and analog-to-digital (A/D) conversion. The book ends with examples of DSP techniques applications to practical problems from several areas.</p>
