Data compression circuit for a digitally - tape recorder (dat)

摘要

it is a datenkompressionsschaltung a digital to analog sound signals tonbandgeru00e4tes proposed a standard mode compressed data in turn if the mode of bandgeru00e4tes 4 channel mode or langspielmodus.the verdichtungsschaltung is a default mode data with a sampling frequency of 48 khz and a number of quantisierungsbits 16 bit, compacting, such of the langspielmodus to create the 32 khz sampling frequency, and the number of quantisierungsbits 12 bit, respectively.therefore, the compressed data on the tape in comparison to the time of the standard mode twice. since the amount of information as a result of the 12 bit linearkompression is reduced, the verdichtungsschaltung also so many channels, such as the reduced information to expand.
