Classify signals into continuous-time vs discrete-time, periodic vs aperiodic, even vs odd, and energy vs power signals. Provide one mathematical example and sketch for each category.

Here are the detailed answers to questions 1 to 5. 1a) Classify signals into continuous-time vs discrete-time, periodic vs aperiodic, even vs odd, and energy vs power signals. Provide one mathematical example and sketch for each category. • Continuous-time vs Discrete-time Signals: Continuous-time signal:* A signal x(t) is continuous-time if it is defined for all real values of time t. It can take on any value over a continuous range of time. Mathematical Example:* x(t) = (2 t) Sketch:* A smooth, unbroken curve.
