  • distorted : 變態的
  • spectrum : n. （pl. -tra ）1. 【物理學】譜，光譜；波譜；能譜，質譜。2. 【無線電】射頻頻譜；無線電（信號）頻譜。3. 【心理學】（眼睛的）余像；殘像。4. 〈轉義〉范圍，幅度；（連續的）系列。
  1. When signals pass high power amplifier, they would be distorted in amplitude and phase, leading to spectrum spread and distortion of in - band signals, both of which would weaken performance of the whole system in turn

    在無線通信中，信號在通過高功率放大器時會產生幅度和相位失真，造成頻譜擴展以及帶內信號畸變，導致整個系統性能的降低。
  2. When the pulse width of input gaussian wave packet was reduced and the length of forbidden region retained, the result displayed the output signal distorted seriously and its spectrum changed very hard. a frequency above the cut - off frequency became the main frequency and the group velocity was below than c

    在保持截止區長度不變，而減小輸入高斯波包的脈沖寬度時，模擬顯示輸出波形嚴重失真，而且，頻譜也發生很大的變化，主頻已變為一高於截止頻率的頻率，群速度小於光速c 。
