1.1 Continuous and Discrete Signals and Systems

Continuous and discrete signals can be related through the sampling operation in the sense that a discrete signal can be obtained by performing sampling on a continuous-time signal with the uniform sampling period as presented in Figure 1.3. Since is a given quantity, we will use in order to simplify notation. f(kT)=f∆[k] t kT f(t) T2 3 T 2T 3T ................
