Question

Which TWO describe digital signal waves?


waves with a larger range of amplitudes


waves represented by a series of numbers


waves that require less encoding and decoding


waves that securely transmit information over long distances


waves that make up most of the sound found in the natural world

Answer 1

- Waves represented by a series of numbers — digital signals are discrete (usually binary) values.

- Waves that securely transmit information over long distances — digital transmission can be regenerated and error-corrected, allowing accurate (and easily encrypted) long‑distance delivery.
