The transmission of broadcasting programs in a digital integrated network
H. Hessenmuller · IEEE Transactions on Audio and Electroacoustics · 1973
If broadcasting programs are to be transmitted in a digital network, 14 bits per sample are necessary to satisfy the noise requirements when linear quantization is applied. The use of an instantaneous compandor allows a reduction from 14 to 10 bits. Good results were obtained with a corresponding experimental system.
