School of Mechanical and Aerospace Engineering MAE 3113 3-2 Introduction to Digital Signals Digital signals are quantized. That is a digital signal is composed of discrete quantities of finite size. Composed of discrete predefined “logic-levels” Signal is defined by a time interval, some times called “bit-interval”. Digital signals may be divided into two categories: Some are inherently both discrete and quantized. Some describe phenomena that are actually continuous in one way or another. The signal must be “interfaced” and quantized in order to make it digital. Analog signals on the other hand are continuous. Infinitely divisible into smaller and smaller parts. A signal that varies with respect to time in a smooth and uniform manner without discontinuities.
