Answer 1

Answer: (a) periodic

Explanation:A signal that varies cyclically with time or repeats itself after a constant interval is called a periodic signal. Periodic signals exhibit a regular, repeating pattern, with a fixed period and amplitude, making them predictable over time. This is in contrast to random signals, which do not repeat in a regular manner.
