Measured signal/quantising-distortion ratio of high-information delta modulation
Measured signal/quantising-distortion ratio (s.q.d.r.) of a high-information delta-modulation codec, both as a function of input level and samplin frequency, is presented. The loss in s.q.d.r. compared with uniform delta modulation is discussed. Meeting requirements on s.q.d.r. is shown to be separable from fulfilling those on dynamic range.
