Book description

Signal Processing in C Written by experts in the field, this invaluable guide provides you with a unified software structure for digital signal processing and numerical analysis in C. Using extensive examples, it clearly explains basic digital signal processing. This book shows you how to develop modular, well structured C code for any DSP application. Signal Processing in C also:

* Provides a wealth of practical, real-world algorithms

* Includes complete coverage of DSP fundamentals such as discrete-time frequency, waveforms, the Nyquist Frequency, aliasing, band pass sampling, and more

* Illuminates theoretical concepts through gradual, step-by-step development of actual C code

* Shows you how to design programs utilizing the most popular signal filtering methods, including Fourier, Fast Fourier, FIR and IIR filters
