This paper proposes a new manner for construction of a piecewise uniform scalar quantizer. Segments' tresholds of the proposed quantizer model are equidistant, whereas the reproduction level number within the segment is different. The proposed quantizer is designed for the Gaussian source. In order to improve performances of the proposed quantizer model, the optimization of the segment tresholds is considered. The main advantage of the proposed quantizer model is its low complexity.
