In purely theoretical disquisitions, often reference is made to ideal conditions that help to simplify things in order to make them more comprehensible. However, one should always bear in mind the physical limits dictated by reality. For example, if we take a square wave [Square wave ] , it certainly makes sense to describe its rate as a series of rectangles. That's if we remain on a theoretical level only, of course. Once we start to speak in real terms however, we find that it is physically impossible to generate a voltage with such sudden transitions, as is the case with rectangles. More realistically, what will occur is that the transitions will be very rapid but not instantaneous. The following diagram illustrates the rate of a real square wave in which the difference between an ideal case and a real case becomes evident:
