Tytuł: Dwustopniowy kwantyzer bazujący na kodowaniu Huffmana pracujący w standardzie G.711
Streszczenie: This paper considers the implementation of Huffman coder for coding of segments of the quantizer based on the G.711 standard. The signal quality obtained with the two-stage quantizer satisfies and overreaches the quality value defined by the G.712 standard, while the implementation of Huffman coder leads to reduction of the average bit rate for 1.25 bit/sample compared to the fixed rate G.711 quantizer. This enables a high quality speech transmission over the channel with less occupancy of its bandwidth.
