Analog data can have only a limited number of defined values.

Analog data take on continuous values, such as the sounds made by a human voice. (correct)

Analog data take on discrete values, such as data stored in computer memory.

Analog data changes without a repeated pattern or cycle.

Analog signals are patterns of signals repeated over identical periods of time, while digital signals have only a few discrete values.

Analog signals have infinitely many levels of intensity over a period of time, while digital signals change without a repeated pattern or cycle. (correct)

Analog signals can have only a limited number of defined values, while digital signals take on continuous values.
