PPT-Basic signals

Why use complex exponentials Because they are useful building blocks which can be used to represent large and useful classes of signals Response of LTI systems to these basic signals is particularly simple and useful. 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 With the exception of the 10 meter BPF the filters are now housed in slightly larger boxes2 inch HWDto lessen component crowding and minimize response degeneration when the cover is installed In January 1996 Tim Duffy K3LR chief operator of one of t Unit impulse function Unit step function Their relation in both continuous and discrete domain We shall even look at the Sifting property of the unit impulse function Basic Signals in detail We now introduce formally some of the basic signals namely brPage 1br EEE3086F Signals and Systems II 212 Page April 14 2014 EEE3086F Signals and Systems II 212 Page April 14 2014 brPage 2br EEE3086F Signals and Systems II 212 Page April 14 201 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 Antti Meriläinen, Edward .
