Analog and Digital Analog and Digital Data amp Signals Periodic amp Aperiodic Signals Contents Information can be voice image numeric data characters or any message that is readable and has meaning to the destination . Stochastic processes Probability theory random processes power spectral dens ity Gaussian process Modulation and encoding Basic modulation techniques and binary data transmission AM FM Pulse Modulation PCM DPCM Delta Modulation Information theory In We will assume here that the independent variable is time denoted by and the dependent variable could be any physical measurementvariable which changes over time think for example of a time varying electric voltage We will denote the generic measur In this lecture we discuss these signals and then proceed to a discussion of sys tems first in general and then in terms of various classes of systems defined by specific system properties The unit step both for continuous and discrete time is zero Analog and Digital.
