Answer
Brief Explanations:
An analog signal represents information by continuously varying its amplitude, frequency, or phase in proportion to the original sound. Digital signals represent information as a sequence of discrete values. Volume is a measure of the loudness of sound and frequency is the number of vibrations per unit time. Only analog signals copy the original sound continuously.
