Answer:
A. 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.
Explanation:
An audio signal can be defined as a representation of sound, either as an analog or digital signals. An analog audio signal refers to a continuous signal that is represented by a changing level of quantity such as voltage with respect to time.
Hence, the statement which best explains how an analog audio signal is typically represented by a computer is that, an analog audio signal is measured at regular intervals i.e it's a time varying quantity. When its measured using a particular measuring device such as audio analyzer, each measurement is stored as a sample, which is then represented at the lowest level as a sequence of bits such as 16kbps, 32kbps, 64kbps, 96kbps, 128kbps, 196kbps, and 320kbps. Kbps means kilobits per seconds.
The option that illustrates the concept of mutual agency is D. Jonah signs a purchase agreement with a supplier while Jaycee agrees to hire a marketing firm to drum up business.
- A Mutual agency simply means a legally binding relationship that is undertaken by business partners whereby each person can make a decision on behalf of the other person.
