Basic operation on Signals - Independent Variables |Problem solving technique|
Download as PPTX, PDF0 likes93 views
This document discusses basic operations that can be performed on digital signals, including time shifting, time folding, time scaling, and amplitude scaling. Time shifting involves delaying or advancing a signal, time folding involves repeating a signal, and time scaling involves compressing or expanding the time axis of a signal. The document also briefly mentions performing arithmetic operations and multiple operations on dependent signal variables.
