Continuous-time periodic signals were introduced in Chap. 2, and in this chapter they are reconsidered as signals defined on ℝ/ℤ(T p ), that is, on a proper quotient group which takes periodicity into account. After the previous analysis of signals defined on ℝ, most of the concepts become obvious. The general rule for the passage from ℝ to ℝ/ℤ(T p ) is to limit the analysis to one period, that is, to a cell of ℝ modulo ℤ(T p ).
