Abstract : The use of delta modulation and deltasigma modulation is considered for the transmission of speech in digital form at digit rates below 40 kb/s. The Variable Slope Delta modulator (VSD-1), and a syllabically companded deltasigma modulator are described, and the results of electrical and subjective measurements to compare their performances are given.
