PPT-Over-complete Representations for Signals/Images

IT 530 Lecture Notes Introduction Complete and overcomplete bases Signals are often represented as a linear combination of basis functions eg Fourier or wavelet representation The basis functions always have the same dimensionality as the discrete signals they represent. 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 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 Oneclock Twoclocks Reachability,PCTL P-complete EXPTIME-complete PTCTL0=1[;] P-complete EXPTIME-complete PTCTL0=1 EXPTIME-complete EXPTIME-complete PTCTL[;] P-hard,inEXPTIME EXPTIME-complete PTCTL Analog and Digital.
