In signal processing, phase distortion or phase-frequency distortion is distortion, that is, change in the shape of the waveform, that occurs when (a) a filter's phase response is not linear over the frequency range of interest, that is, the phase shift introduced by a circuit or device is not directly proportional to frequency, or (b) the zero-frequency intercept of the phase-frequency characteristic is not 0 or an integral multiple of 2π radians.

  • تشويه الطور في معالجة الإشارات، هو تشويه الطور أو ما يسمى بتشويه تردد الطور وهو تشويه، أي تغيير في شكل الموجة، يحدث عندما لا توجد استجابة طور (أ) المرشح للتيار المتردد ليست خطية على مدى التردد المعني أي أن إنزياح الطور الذي أدخلته دائرة أو جهاز لا يتناسب طرديًا مع التردد، أو في الطور (ب) عندما لا يكون اعتراض التردد الصفري لخاصية تردد الطور صفراً أو مضاعفاً لا يتجزأ من 2π راديان.

  • In teoria dei segnali, la distorsione di fase o distorsione frequenza-fase è una distorsione, cioè un cambiamento della forma d'onda, che si verifica quando (a) la risposta di fase di un filtro è non lineare sull'intervallo di frequenze di interesse, cioè lo spostamento in fase introdotto da un circuito o da un dispositivo non è direttamente proporzionale alla frequenza, oppure (b) l'intercetta (sull'asse delle ordinate, che è l'asse delle fasi) a frequenza zero della caratteristica frequenza-fase non è 0 né un multiplo intero di 2π radianti.
