Digital signal processing

The contents of this book are introduction of digital signal processing, continuous time signal and transform with fourier series, Laplace function and impulse function, sampling on sampling theory, restore of continuous signal out of sampling and A/D transform, Discrete time signal and transform about transform of discrete fourier, cutting and leaking a spectrum and transform of fast fourier transform, Z transform on relationship of Z transform and laplace transform, Discrete time system with frequency response and system implementation, Design of finite impulse response filter about characteristic of F/R filter and optimization way, and Design of infinite impulse response filter.
