Sections 1.3 0 Exponential and Sinusoidal Signals
Exponential and Sinusoidal Signals † They arise frequently in applications, and many other signals can be constructed from them. Continuous-time complex exponential and sinusoidal signals: x(t) = Ceat where C and a are in general complex numbers. Real exponential signals: C and a are reals. 0 0 C t Ce at C>0 and a>0. 0 0 C t Ce at C>0 and a<0.
