* VIDEO: Signal Operation
Basic signal operations include time shifting, scaling, and reversal. In this video, a continuous-time signal x(t) is sketched and then 4 different signal operation examples are demonstrated. Time shifting, compression, expansion, and reversal are all considered individually.
The previous video considered signal operations such as time shifting and time compression performed individually. In this video, a combined operation consisting of both a time shift and compression are considered. The original signal is sketched, and then the time-shifted time-compressed signal is derived and sketched.
