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

fundamental frequency n. (a) Music and Acoustics the frequency of the lowest tone that an object can produce by resonant oscillation where the whole body is vibrating together, of which the harmonic frequencies are multiples (cf. sense A. 7b); (b) Physics (in a complex periodic waveform) the greatest common factor of the frequencies of each sinusoidal component (cf. Fourier's law at Fourier n.).
