Course Notes - Purdue University College of Engineering
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
Discrete-Time Signals and Systems - Pearson
www.pearsonhighered.com12 Chapter 2 Discrete-Time Signals and Systems guarantees that the original signal can be reconstructed as accurately as desired from a corresponding sequence of samples if the samples are taken frequently enough. In discussing the theory of discrete-time signals and systems, several basic se-quences are of particular importance.

Part 1. THEORY Instantaneous power of continuous-time signals: Let !" be a real (i.e. no imaginary part) signal. If !"
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 ...
