K. D. Pavate, K.V. Ramakrishnan · IETE Journal of Research · 1982
Low bit rate digital transmission of speech signals continues to hold the attention of engineers and scientists working in the area of communications. This paper examines the basic issues involved in band-width compression techniques. The maximum information rate in speech signals has been reviewed and an upper limit for low bit rate digitization arrived at. Some of the existing low bit rate speech digitization systems are reviewed and discussed.
