Abstract
The invention relates to transmission systems with dynamic compansion for the coded transmission of speech signals. By the use of a limiting device in the dynamic control circuit of the receiver the intelligibility is improved. The limiting device is such that the dynamic range of a transmitted signal is limited so that no relevant information is lost in the period the human ear needs to adapt itself to rapid sound variations.
