the fundamental should be at least in the second frequency bin. Higher harmonics are at integer multiples of the fundamental frequency. If a harmonic lies within the monotonically decreasing region in the neighborhood of another, its power is considered to belong to the larger harmonic. This larger...

ADC的SNR:位数究竟在哪? 摘要:理论上,一个ADC的SNR(信号与噪声的比值)等于(6.02N+1.76)dB,这里N等于ADC的位数。虽然我的数学技巧有点生疏,但我认为任何一个16位转换器的信噪比应该是98.08dB。但当我查看模数转换器 的数据手册时,我看到一些不同的情况。比如,16位的(逐次逼近型)模数转换器指标的典型值通常可...
The percentage of the shrunken seeds of J-1, J-2 and J-3 were 43.69%, 60.80% and 45.87% respectively, which were significantly higher than that of WT(8.43%). The weight of 1 000 seeds decreased by 27.95% to 29.32% compared with the wild-type, with a...
With non-coherent integration we smooth out the noise, but we do not reduce the noise power, so unless the carrier power is significantly higher than the power in the noise we will not find the carrier, no matter how many non-coherent samples we use in the filter. ...
frequency, which is higher than most frequencies in a seismic wave. It also has a high damping ratio (60% of critical). At this damping level, the frequency response approaches the Butterworth maximally flat magnitude filter, and phase angles are pre- ...
最新世代のテクノロジーは、前世代および競合ソリューションと比較して10倍高いSNR性能と10分の1の消費電力を実現します。 PSoC™ 4000Tは常時オンのタッチ センシング機能を備え、アクティブ時とスタンバイ時の消費電力を低く抑えたヒューマン マシン インターフェイス (HMI) 操作を可能に...
front page of their data sheets, and, frankly, an SNR of 95 dB for a 16-bit SAR converter is competitive. Unless I am wrong, the 98.08 dB I calculate is higher than the 95-dB specification that I find with the best of the 16-bit-converter data sheets. So, where did the bits go...
A higher SNR value means the signal is clearer. With a lower value, you start to introduce Gaussian noise into your network (expressed as static), and as the number becomes closer to 1, the worse the static gets. The noise interferes with the signal processing capabilities of your network,...
Experimental results show that this algorithm can detect small targets within the IR image sequence which SNR is bigger than 2. 0. 实验结果表明,该算法能够从信噪比大于2.0的图像序列中检测出目标。 www.magsci.org 9. In addition, since the pulse lengths are shorter with higher RF bandwidths, the...
