An oceanographer uses an underwater hydrophone to capture a whale's low-frequency vocalisation. The hydrophone registers this sound as a continuous electrical signal (voltage representing acoustic pressure waves), as shown in the analogue-to-digital diagram below:
Describe the sequence of steps required to convert this continuous analogue voltage signal into a digital format suitable for storage on a marine data logger.
