Questions and Answers
What are the two types of sinusoidal signals discussed in the lecture?
The two types of sinusoidal signals discussed in the lecture are continuous-time and discrete-time sinusoidal signals.
What is the significance of sinusoidal signals in signal processing?
Sinusoidal signals serve as important building blocks for more general signals and provide a powerful set of ideas for representing signals and analyzing systems.
What is the distinction between continuous-time and discrete-time sinusoidal signals?
Continuous-time sinusoids are always periodic, while discrete-time sinusoids may or may not be periodic.
