说明：  預失真是一種用於改善無線電發射機放大器線性度的技術。大多數電信系統中的無線電發射機放大器需要是“線性的”，因為它們必須準確地再現其輸入端存在的信號。 壓縮其輸入或具有非線性輸入/輸出關係的放大器導致輸出信號濺到相鄰的射頻上。 這會對其他無線電信道造成乾擾。(Predistortion is a technique used to improve the linearity of radio transmitter amplifiers. Radio transmitter amplifiers in most telecommunications systems are required to be "linear", in that they must accurately reproduce the signal present at their input. An amplifier that compresses its input or has a non-linear input/output relationship causes the output signal to splatter onto adjacent radio frequencies. This causes interference on other radio channels.)
