Noise power spectral density measurement were performed on single-strip patterned NiFeCo-Cu giant magnetoresistance (GMR) multilayers with various width ranging from 2 /spl mu/m to 20 /spl mu/m. The measurements were carried out over two frequency ranges from 0.1 Hz to 100 Hz and 10 Hz to...
1) noise spectral power density 噪声功率频谱密度2) noise power density spectrum 噪声功率密度谱 1. Based on quantum theory of light, the noise power density spectrum and its timespectrum formula of the intensity fluctuation of a two-mode laser are derived. 采用光场的量子理论导出了自由运转...
There are no good data on low frequency (less than 0.1 Hz) power spectral density (PSD) for the Q-Flex accelerometer. However, some preliminary stability measurements were made over periods of 12 to 24 hours and demonstrated stability less than 0.5 micro-g over greater than 12 hours. The ...
