The pre-emphasis improves the apparent signal-to-noise ratio by making use of the iev dynamic range. The standard also specifies the form of audio encoding, 2-channel signed bit Linear PCM sampled at 44, Hz. There was a debate over the use of bit or bit quantization.

August Replaced By: These parameters are common to all discs and used by all logical formats. Philips found a way to produce bit quality using its bit DAC by using four times oversampling, some CDs are mastered with pre-emphasis, an artificial boost of high irc frequencies.

This technology could store six samples in a horizontal line. The exact sampling rate of 44, the device that converts an analog audio signal into PCM audio, which in turn is changed into an analog video signal is called a PCM adaptor.

The Nyquist—Shannon sampling theorem states that a rate of more than twice the maximum frequency of the signal to be recorded is needed. Although rarely used, the specification allows for discs to be mastered with a form of emphasis, the second edition of IEC was published in and it cancels and replaces the first edition, amendment 1 and the corrigendum to amendment 1.

The standard is defined in the Red Book, one of a series of Rainbow Books that contain the specifications for all Compact Disc formats.
