9 mark for review which of the following best explains how an analog audio signal is typically represented by a computer? a an analog audio signal is measured as input parameters to a program or procedure. the inputs are represented at the lowest level as a collection of variables. b an analog audio signal is measured at regular intervals. each measurement is stored as a sample, which is represented at the lowest level as a sequence of bits. c an analog audio signal is measured as a sequence of operations that describe how the sound can be reproduced. the operations are represented at the lowest level as programming instructions. d an analog audio signal is measured as text that describes the attributes of the sound. the text is represented at the lowest level as a string.

Answer

Brief Explanations:

To represent an analog audio signal in a computer, it is sampled at regular intervals. These samples are then converted into digital form and stored as sequences of bits at the lowest - level representation. Option A is incorrect as audio signals are not typically input parameters to a program in that way. Option C is wrong because audio is not represented as a sequence of operations for reproduction at the lowest level. Option D is incorrect since audio is not represented as text describing sound attributes at the lowest level.

Answer:

B. An analog audio signal is measured at regular intervals. Each measurement is stored as a sample, which is represented at the lowest level as a sequence of bits.
