PPT-SIGNALS

REQUIREMENTS OF SIGNALS Should be visible from long distances Should not vary in character and should possible to identify Should be simple for identification amp make its meaning clear at a glance. 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 Specifically we discuss both continuous time and discretetime sinusoidal signals as well as real and complex expo nentials Sinusoidal signals for both continuous time and discrete time will be come important building blocks for more general signals 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 These component signals are carried on multiple coaxes RGB component provides the ultimate analog picture quality It is possible to use a 15Pin to BNC connec tion cable with the BNCs into the component input and the 15pin connector into VGA output A Mahmoud. .
