What is an analog audio signal?

Analog audio signals are alternating current (AC) electrical voltages, meaning they constantly reverse polarity from positive to negative. The rate of this oscillation determines the frequency of the signal, which can vary from less than 20 times a second (20Hz) to more than 22,000 (22kHz), the range of human hearing.

How is analog audio signal measured?

Analog levels are usually measured in voltage ratios such as dBu (decibel unloaded) or dBV (decibel voltage). Since dBu and dBV both describe continuous positive and negative voltage changes, analog signal levels are expressed in average RMS levels.

Which of the following is an example of an analog audio?

Vinyl records, cassette tapes and 8-track are examples of analog distribution media.
