A method for designing a rate-distortion optimum scalar quantizer is developed, and the performance of the optimum quantizer is compared with that of linear quantizers using means square error and output entropy, for a simple class of probability density function (pdf). The simple class means that pdf is unimodal and symmetric about its mode value, and is differentiable in both sides of symmetry. The method proposed here is based on solving the Kuhn-Tucker condition.
