PPT-Digital Signals and Systems

1 A discretetime signal is a function of an integer variable In the DS processor the signal is represented by the discrete encoded values with a finite precision   Digital Signals Graphical representation of a discretetime signal. 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 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.
