由图2.7(b),我们观察到1/f的噪声谱到输出口的增益的为(gmro)^2;热噪声,In^2,仅仅是乘了个ro^2。我们得到: 图2.7(c),log-log画出的频谱曲线,可将闪烁噪声显示成随着频率线性下降。1/f和热噪声的交点为fc,称为 corner frequency,作为衡量噪声水平的标准。纳米级CMOS工艺中,fc在50~100MHz之间,除非管子...
Artificial neural networks can be used effectively to filter out noise from frequency shift keying (FSK) and phase shift keying (PSK) modulation signals corrupted with random noise. In the present paper, the time and frequency domain filtering schemes are investigated. The number of data points ar...
Based on the observation that sinusoids show themselves as outliers in frequency domain,this paper proposes a new approach for the superresolution frequency estimation of sinusoids in an unknown colored noise environment by utilizing the capability of running median filters to remove outliers from data....

Spectral and temporal noise shaping are then used to minimize the perception of noise in frequency and in time. Initial experiments at 16 kb/s demonstrate the validity of shaping the noise in time as well as in frequency.关键词: Bit rate Fasteners Frequency domain analysis Noise shaping Phase ...
Techniques may improve upon prior art by calculating SNR values in a more color noise insensitive manner in the frequency domain. An agent may be implemented to calculate SNR values and either store or use the SNR values to modify operational parameters in communicative system....
