INTRODUCTION TO DIGITAL SIGNAL PROCESSING
1.0 DIGITAL SIGNAL PROCESSING What do we mean by "Digital Signal Processing"? DIGITAL - means discrete in nature – i.e. the signal levels are chosen from a finite set of levels, as opposed to continuous or analog signals, which can have an infinite number of levels. In practice, digital nearly always means binary, that is, two-level
