In present-day communication systems, most data is sent in digital form instead of analogue form. Suggest three advantages of transmitting data in digital form.
Suggest the effect on the quality of the recording of sampling at a high frequency rather than a lower frequency.
Suggest the effect on the quality of the recording of using a long word length rather than a shorter word length.
A recording lasts for a total of $5$ minutes $40$ seconds. Calculate the number of bits produced during the recording. The music is sampled at $44.1\,\text{kHz}$ and each sample has a $16$-bit word.
