مجال التردد

The Fourier transform converts the function's time-domain representation, shown in red, to the function's frequency-domain representation, shown in blue. The component frequencies, spread across the frequency spectrum, are represented as peaks in the frequency domain.

في الإلكترونيات و هندسة التحكم، مجال التردد Frequency domain يستخدم لتمثيل إشارة عبر دالة رياضية بدلالة التردد،عوضا عن الزمن.
