engineering.purdue.edudigital video. One can obtain discrete-time signals by sampling continuous-time signals (i.e., by selecting only the values of the continuous-time signal at certain intervals). Just as with signals, we can consider continuous-time systems and discrete-time systems. Examples of the former include atmospheric, physical, electrical
Sampling and Reconstruction - Ptolemy Project
ptolemy.berkeley.eduChapter 11 Sampling and Reconstruction Digital hardware, including computers, take actions in discrete steps. So they can deal with discrete-time signals, but they cannot directly handle the continuous-time signals that are prevalent in the physical world. This chapter is about the interface between these two worlds, one continuous, the other ...
9.6 Correlation of Discrete-Time Signals - Rutgers University
eceweb1.rutgers.edu9.6 Correlation of Discrete-Time Signals A signal operation similar to signal convolution, but with completely different physical meaning, is signal correlation. The signal correlation operation can be performed either with one signal (autocorrelation) or between two different signals (crosscorrelation).

Chapter 2: Introduction to Point Processes
www.stat.columbia.eduChapter 2: Introduction to Point Processes I. Point processes are used to describe data that are localized in space or time In Chapter 1, we saw an example of neuronal activity in the supplemental eye field (SEF) expressed in terms of a raster plot and a peri-stimulus time histogram (Fig. 1.1).
