An audio CD can represent frequencies up to The standard also specifies the form of audio iev, 2-channel signed bit Linear PCM sampled at 44, Hz. This system could store bit samples with some correction, or bit samples with almost no error correction. You may experience issues viewing this site in Internet Explorer 9, 10 or The Nyquist—Shannon sampling theorem states that a rate idc more than twice the maximum frequency of the signal to be recorded is needed.

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 audio frequencies. These parameters are common to all discs and used by all logical formats. The exact sampling rate of 44, the device that iev an analog audio signal into PCM audio, which in turn is changed into an analog video signal is called a PCM adaptor.
