Filters have a lot going for them. In the previous chapter we have seen that they are simple to design, describe and implement. So why bother devoting an entire chapter to the subject of systems that are not filters? There are two good reasons to study nonfilters-systems that are either nonlinear, or not time-invariant, or both. First, no system in the real world is ever perfectly linear; all ‘linear’ analog systems are nonlinear if you look carefully enough, and digital signals become nonlinear
