Electronic Signal Generation

An electrical analogue audio signal is generated from the pressure of an atmosphere impacting upon a transducer. The transducer converts the rapid atmospheric fluctuations into an alternating voltage. An audio analogue signal is represented as a fluctuating voltage that alternates from positive to negative. This alternation is known as the cycle of the wave and is measured in Hertz (Hz). A sound's Frequency is the rate at which it vibrates, or its cycles per second. A cycle consists of movement from a starting point (0) through both positive and negative amplitudes, eventually returning to the starting point. A sound's frequency determines its pitch. The decibel (abbreviated as dB) is a unit used to represent a ratio between two numbers using a logarithmic scale. For example, when comparing the numbers 14 and 7, you could say 14 is two times greater than the number 7 or you could say 14 is 6 dB greater than the number 7. Engineers use the equation dB = 20 x log (V1/V2) when comparing two instantaneous values. Decibels are commonly used when dealing with sound because the ear perceives loudness in a logarithmic scale. To double the amplitude of a sound, you apply a 6 dB gain.

Digital Audio Signal Generation

In digital audio, a signal is not captured in a continuous fashion, as in a traditional analogue recording. To digitise a sound, a number of snapshots, or samples, are taken every second, from an analogue signal. This number is a product of the sampling rate and is changed into binary representations of the analogue signal.
