Fourier transformatsiyasi - vaqt funksiyasini (yoki makon) uning tarkibiy chastotalariga ajratish uchun ishlatiladigan matematik vosita va signalni qayta ishlashda, audio va tasvirni siqish va boshqa ko'plab sohalarda keng qo'llaniladi. Funksiyaning uzluksiz Fourier transformatsiyasi (CFT) quyidagicha belgilanadi: F (x) = ∫∞∞f (x) = e (x) = e (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f (x) = f
