Abstract :
The distortion between input and output of uniform quantizers is investigated for a Gaussian input probability density and for the magnitude-error distortion measure. The minimization of this distortion leads to optimum uniform quantizers. A set of universal curves relating the distortion to the spacing of the thresholds is given. The usefulness of these curves is demonstrated in the solution of a few practica1 problems.
