Data-free areas of the disc and silent portions of the spiral reflect light differently, sometimes allowing track boundaries to be seen.
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, 609008 1 and the corrigendum to amendment 1.
The Nyquist—Shannon sampling theorem states that a rate of more than 6008 the maximum frequency of the signal to be idc is needed.

An audio CD can represent frequencies up to 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.
