Digital Signal Processing (DSP) is a powerful technology that will shape science in the twenty - first century . Changes have already been made in various fields of study : communications, medical imaging, and high fidelity music reproduction, to name just a few. Each of these disciplines has developed a deep DSP technology, with its own algorithms and specialized techniques. This combination of breadth and depth makes it impossible for any one individual to master all of the DSP technology that has been developed. Therefore , DSP education involves two tasks: learning general concepts that apply to the field as a whole , and learning specialized techniques for your particular area of interest. The first chapter of the book describes the effects that DSP has made in several diverse fields. (Steven W. Smith, 1999)
Term
Definition
Translation
ADC
analog-to-digital converter, a system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal
