Overview of Digital Signal Processing Theory
Abstract
An overview of the theory of digital signal processing is presented here using key portions of the applicable technical literature. This can serve either as an introduction for those who desire to pursue the subject further or as a concise summary for those for whom more detailed investigation would be impractical. The discussion begins with a consideration of discrete systems and signals as well as their relationship to the continuous case. The realization of digital signal processing systems in the form of digital networks is presented. Theory and design of digital filters are discussed along with their relation to continuous filter characteristics. The discrete Fourier transform (DFT) and its efficient implementation in the form of the fast Fourier transform (FFT) are presented. Discrete convolution and correlation and the application of the FFT to their efficient implementation are described. Finallly the quantization effects inherent in all digital signal-processing realizations are reviewed with respect to their influence on digital-filter and FFT outputs.
