Explanation:
Detailed explanation-1: -Explanation: Propagation time is directly proportional to square of the Propagation distance (x2). It is the time taken by the signal to move from input port to output port.
Detailed explanation-2: -Time is plotted along the horizontal axis, so horizontal “distances” along the graph represent amounts of time.
Detailed explanation-3: -A periodic composite signal can be decomposed into a series of simple sine waves with discrete frequencies-frequencies that have integer values (1, 2, 3, and so on).
