This video explains beautifully the concept of Time Scaling and Amplitude Scaling of Signals. The basics are made clear by plotting graph of trigonometric functions. For better understanding many graphs are plotted for examples like Graph of sinx, Graph of sin 2x, Graph of sin(x/2), Graph of 2sinx, and Graph of sinx/2 .
