Quantity_SNR_Compare
均匀量化和非均匀量化在性能上存在着显著的差异,这种差异可以用信号通过量化器后的量躁比来反映出来。本程序用曲线表示了理论和实际两个方面下两种量化的量躁比。从而可观察他们的性能上的差别。(There are significant differences with the function between Uniform quantization and non-uniform quantization ,which can be quantified by SNR from the quantizer.This program use the curves to denote the SNR of theory and practical signal.Then we can observe the performance of the differences.)

用Welch法进行功率谱估计
考虑L的三个不同值:L=256(3个数据段),L=128(7个数据段)和L=64(15个数据段)。各自的谱估计图如上图所示。可以明显的看到,加窗明显的减小了频谱上的假谱峰,但也更加进一步平滑了谱峰。所以,对于L=64的情况,在ω=0.8π的谱线可以很确定的辨认,但是那两个靠近的谱峰不容易区分。对于L=128的情况,这种情况提供了在分离和检测间最好的均衡。当然,对于在L=256时的情况,效果是更好的,能够从谱估计图上明显的分辨出三条谱线的存在以及它们幅度关系的强弱。 除了Welch法外,还可以采用对多个周期图求平均的功率谱估计方法的其他方法如Bartlett法等等,在功率谱估计上也能取得较好的结果。(consider three different values : L = 256 (3 data), L = 128 (7 data) and L = 64 (15 data). Their spectral estimation map as shown in Fig. It is clear to see that increase significantly decreasing window of the spectrum of false peaks, but much more to further smooth the peaks. Therefore, L = 64, in the case = 0.8 spectrum can determine the identification, but that the two peaks around is not easy to distinguish. L = 128 for the situation, which provided the separation and detection among the best balanced. Of course, L = 256 in the case, the effect is better, from the spectral estimation map clearly distinguish between the three lines of the existence and their relationship to the rate of strength. In addition to Welch law, but also can be used to map multiple cycle for the average power)
