Period is a general term used to denote an interval of time, but the word period has special meaning in frequency analysis. By the period of a repeating process, we mean the shortest time interval for which the process exactly repeats itself. In our example of the rotating vector, the motion exactly repeats itself 10 times a second, so we say that it has a period . What does this have to do with the subject of frequency?
