The present invention relates to a high capacity, high signal- to-noise ratio sensor incorporating an array of Bragg grating transducers photoinscribed on a dielectric guide and a feedback loop incorporating a wavelength selective element which is time modulated making it possible to obtain a laser...
Signal-to-noise ratio (SNR) Total harmonic distortion (THD, THD+N) Coherence Crest factor and rms, peak, and peak-to-peak signal levels Signal mean, variance, and standard deviation values Flat, A, and C-weighted equivalent (Leq), time-weighted (Lp), and percentile-exceeded (Lx) sound ...
接收機雜訊來自兩個方面，一是天線接收到的雜訊，二是接收機自身產生的雜訊。天線接收到的雜訊包括天空雜訊（skynoise），大氣雜訊（atmosphericnoise），地球雜訊（earthnoise）、銀河雜訊（galacticnoise）和人工雜訊（man-madenoise）。天空雜訊的雜訊功率可表示為 NkTAB 式中B是頻寬，k=1.3810–23J/K，是...
3. The high value of signal to noise ratio, to make sure get a better sound with high fidelity. 4. The new circuit design, adopts the SMT surface mount technology, to improve the consistency and efficiency of the machine. 5. Class AB circuit design, advanced pow...
Compared with the application of laser emission light, the notch filter is very important. In order to obtain a good signal-to-noise ratio in spectral experiments, it is very important to suppress the pumped laser. The notch filter is made of a dielectric film deposited on a polished glass ...
verygood与verywell的区别如下：1. good,well 形容词都有“好”的意思,good是通用词，可以表示各种品质方面的优异，从美学到道德规范几乎都可以使用。It's an old film, but it's very good.那是一部老电影，但是很好。well表示身体“无病的”，“健康的”You look very well, Jimmy.你看...
射频微波设计概论(RF系统讲解详明-GOOD)無線通訊是近年射頻與微波電路發展的最大推動力1 典型的GSM移動通信系統 無線通訊系統發射機、接收機離不開射頻與微波電路2 任何無線通訊系統都包括發射機和接收機兩個基本部分。發射機的功能是將信號調變到載波上，並由天線輻射出去。接收機的功能則相反，將天線接收到的載入在...

However, as soon as enough noise is added to the input signal, so that there is more than one code in the histogram, the averaging method starts working again. Thus—interestingly—some small amount of noise is good (at least with respect to the averaging method); however, the more noise...
