Fourier transform
常見例句
- That s part of what makes Fourier wonderful. Nonetheless, for some signal-processing applications, banded matrices could prove more efficient than the Fourier transform.
那是傅里葉變換美妙的部分,但對于某些信號處理應(yīng)用來說,帶狀矩陣可以比傅里葉變換更加高效。 - 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“快速傅里葉變換”把一束激光中的超過300中不同的光的顏色的光分解出來,每一種光被編碼成它自己的信息串。 - Each of its pixels is sensitive to specific incident angles and supplies a component of the mathematical operation called the Fourier Transform to produce an image about 20 pixels across.
它的每一個像素點(diǎn)都對指定的入射角十分敏感,并提供一部分稱為“傅里葉變換”的數(shù)學(xué)運(yùn)算以產(chǎn)生一張20像素的圖像。 - 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.
