摘要:A method of encoding/decoding a digital signal using linear quantization by
sections, and an apparatus for the same are provided. The method of encoding includes:converting a digital input signal, and removing redundant information from the digitalsignal; allocating a number of bits allocated to each predetermined quantized unitconsidering the importance of the digital signal; dividing the distribution of signal valuesinto predetermined sections based on the predetermined quantized units, and linearquantizing data converted pin the operation of converting the digital input signal bysections; and generating a bit stream from the linear quantized data and predeterminedside information. Therefore, a sound quality is improved compared to a sound qualityproduced by conventional linear quantizing devices and a complexity of a non-linearquantizing device is reduced.
