DSP Overview

DSP (Digital Signal Processing)

Digital Signal Processing is a very challenging field. Digital signal processing (DSP) is concerned with digital representation of signals and use of digital hardware to analyze, modify or extract information from these signals. DSP includes audio and speech signal processing, digital image processing, statistical signal processing, signal processing for communications, control of systems, biomedical signal processing, seismic data processing, etc. There are many advantages in using digital techniques for signal processing rather than traditional analog devices such as Flexibility ,Reproducibility,Reliability.
