dynamic comparation
abstract: In many cases, a wide dynamic range is an essential aspect of a signal, something to be preserved at all costs. This is true, for example, in the high-quality reproductionof music and in communications systems. However, it is often necessary to compress the signal to a smaller range without any significant loss of information.
Compression is often used in magnetic recording, where the upper end of the
dynamic range is limited by tape saturation, and the lower end by the granularity of the medium.
