Sin wave is |
| A. | aperiodic signal |
| B. | periodic signal |
| C. | random signal |
| D. | deterministic signal |
| Answer» B. periodic signal | |
| Explanation: periodic signal is that which repeats itself after a regular interval. sin wave is a periodic function since it’s value can be determined at any point of time, as it repeats itself at a regular interval. aperiodic signal does not repeat itself at regular interval of time. random signals are the signals which have uncertain values at any time. while deterministic signals are the signals which are constant over a period of time. | |
