fast Fourier transform

常見(jiàn)例句

雙語(yǔ)例句

• The trick is to use what is known as a "fast Fourier transform" to unpick more than 300 separate colours of light in a laser beam, each encoded with its own string of information.
  這種技術(shù)是使用“快速傅裡葉變換”把一束激光中的超過(guò)300中不同的光的顔色的光分解出來(lái)，每一種光被編碼成它自己的信息串。
• In the current experiment, the team sent their signals down 50km of optical fibre and then implemented what is known as an optical fast Fourier transform to unpick the data streams.
  在這兒，研究者們採(cǎi)用一種被稱爲(wèi)光學(xué)快速傅裡葉變換的方法來(lái)分離出數(shù)據(jù)流。
• Experimental results show that this method achieves the same accurate level as classic fast Fourier transform (FFT) based method with invariance to illumination change and lower computation costs.
  實(shí)騐結(jié)果表明該算法相對(duì)傳統(tǒng)基於快速傅立葉變換法具有同等精度、抗光照變化及計(jì)算量少的特點(diǎn)。

• The new single-laser fiber-optic speed record was set using a technique called fast Fourier transform that pulses light at an incredibly high rate with data encoded in 325 distinct colors across the spectrum.
