頻帶內失真 的英文怎麼說
中文拼音 [bīndàinèishīzhēn]
頻帶內失真
英文
inband distortion-
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。In this paper, a new advanced general wide - band signal generator module is developed, which uses high speed fpga as its control - unit. the module can work in any system with different bandwidth and can generate any kind of lfm signal, whose bandwidth is less than 200mhz, and time - width is less than 870us
該模塊具有標準的輸入輸出介面，不同波段、不同帶寬的雷達系統均能直接使用，可以產生帶寬200mhz以內、脈沖寬度870us以內的線性調頻信號，具有預失真功能，能補償系統的特性特性失真，還可直接通過4倍頻或8倍頻實現帶寬的擴展。
