Signals and Systems: Part I In this lecture, we consider a number of basic signals that will be important building blocks later in the course. Specifically, we discuss both continuous-time and discrete-time sinusoidal signals as well as real and complex expo-nentials. Sinusoidal signals for both continuous time and discrete time will be-

In discussing the theory of discrete-time signals and systems, several basic se-quences are of particular importance.
