Introduction to Digital Signal Processing provides a thorough introduction to the subject of digital signal processing, with emphasis on fundamental concepts and applications of discrete-time systems, and the synthesis of these systems to meet specification in the time and frequency domains. Topics covered include characterization of discrete time signals and systems, linear difference equations, solutions by recursive algorithms, convolution, time domain analysis, sampling theory, frequency domain analysis, discrete Fourier series, design of FIR and IIR filters, and practical methods for hardware implementation.
