R&D Report 1976-28 : Hadamard transformation: Assessment of bit-rate reduction methods. C.K.P. Clarke This report is concerned with the bit-rate reduction of signals produced by Walsh-Hadamard transformation of PCM television signals. The main characteristics of the transform signals are outlined and the methods of linear and non-linear coding used to reduce their bit rate are described. It was found that, with linear coding, a slightly higher bit rate is required to describe the transform...
