Baris ka-48: Satiap [[gelombang nu henteu-sinusoida]], saperti [[gelombang kotak]] atawa malah gelombang sora anu henteu teratur anu nyusun [[Speech communication\|ucapan]] manusa, bisa dinyatakeun sabage sakumpulan gelombang sinusoida kalayan [[periodicity\|perioda]] sarta [[frequency\|frekuensi]] anu beda-beda anu dicampurkeun babarengan. Teknik ngarobah wangunan gelombang kompleks jadi komponen-komponen sinusoidana disebut [[analisis Fourier]].

The human [[ear]] can recognize single sine waves because sounds with such a waveform sound "clean" or "clear" to humans; some sounds that approximate a pure sine wave are [[whistling]], a [[crystal glass]] set to vibrate by running a wet finger around its rim, and the sound made by a [[tuning fork]]. ==Deret Fourier== ~~To the human ear, a sound that is made up of more than one sine wave will either sound "noisy" or will have detectable [[harmonics]]; this may be described as a different [[timbre]].~~ Dina taun 1822, [[Joseph Fourier]], saurang ahli matematika Perancis, manggihan yen gelombang-gelombang sinusoida bisa digunakeun sabage building block anu saderhana pikeun 'nyusun' sarta ngagambarkeun ampir sakabeh wangunan gelombang periodic. Prosesna disebut [[analisis Fourier]], anu ngarupakeun alat analitis anu mangfaat dina tolab ngeunaan gelombang, aliran panas, widang ilmiah sejenna, sarta teori [[pamrosesan sinyal]].
