7.1 Statistical Characteristics of Noise 噪声不可测, 但the average power of noise可测. 平均power的定义: Pav=1T∫0TV(t)2dt 7.1.1 Noise Spectrum 我们关心power spectral density(PSD), 即在每个频率点上noise power的大小 在频率domain 分析: Power Spectral Density (PSD) = Vrms^2/fres = V^2/Hz...
女声高亢(高频分量功率大) 信号与系统中用傅里叶变换得到噪声的频谱密度,再对频谱密度进行平方,得到的称之为能量的谱密度(Energy Spectrum Density,ESD);利用极限的概念,得到功率谱密度(Power Spectral Density,PSD)。 换句话说,功率谱密度体现了:噪声各个频率分量的功率在不同的频率下分布。 1.1直观物理意义 让噪声...

noisepsdOut = noisepsd(sysobj,L) computes the power spectral density (PSD) of filter output occurring because of round-off noise. The round-off noise is produced by quantization errors within the filter. The PSD is computed as an average over the L trials. noisepsdOut = noisepsd(___,Na...
We have studied the noise power spectral density S(f, T) in YBa_2Cu_3O_(7-delta) thin films. Measurements were performed for various magnetic field, up to 14 T. and in a large range of temperatures. We found that in thin films deposed by the laser ablation method on the surface (...
