T-Law: A New Suggestion for Signal Companding

In this paper we propose a new method for companding a discrete signal, by a process we will call by the name of T-Law. When this data is processed according to the discussed technique, it gives much less average quantization noise than both μ and A-laws. The technique proposed requires much less number of calculations when comapared with μ and A-laws. T-Law can also be applied for companding realtime signals.
