The function of compressor is to non-uniformly quantize the pump culture after compression, that is to say, the sampling signal is non-linearly compressed at the transmitting end and then uniformly quantized. Thus, the compressor is characterized in that the slope of the small signal is greater than 1 and the slope of the signal is less than 1. This effect is to improve the quantization signal-to-noise ratio of small signal by reducing the quantization signal-to-noise ratio of large signal, so that the signal is in a dynamic range without increasing the quantization series.
+ 1260△= 1024△+64△*3+44△
1260 > 1024, so it is located in the eighth section, and the section number is11.
The look-up table of code in the segment shows 00 1 1, so the output code is111.
The quantization level is selected in the quantization interval,
So the quantization level is1024 △+64 △ * 3+32 △ =1248 △.
So the quantization error is1260 △-124 △ 8 =12 △.
1260 binary transformation, the answer is? 100 1 1 10 1 100
