英语词汇“noise spectrum”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

noise spectrum n. the frequency spectrum of noise (in sense 12a), or of a component of an oscillation considered to be noise; (also) a frequency spectrum that is characteristic of noise, typically having a randomly fluctuating amplitude over a continuous range of frequencies.

ΚΠ

1941 Electronic Engin. 14 537/3 Signal-to-noise ratio is greater [for phase modulation] than for amplitude modulation..though it is less than for frequency modulation since the triangular noise spectrum effect is absent because noise itself phase modulates the carrier.

1990 Compact Disc 7 Aug. 37/3 A full-range noise-spectrum analysis showed that the noise energy (in approximately one-third-octave bands) was at a constant −130 d b up to 500 hz, rising slowly to −118 d b at 20,000 hz.
