video modulator 中文意思是什麼
video modulator
解釋
視頻調制器-
This modulator works with the guided - wave reflectance peak, in which the light intensity is changed by the variation of the refractive index of poled polymer due to the electro - optic effects. device performances have been theoretically and experimentally investigated. we also successfully carried out experiments of video signal transmission using the proposed modulator
該調制器工作于金屬包覆波導的衰減全反射導模吸收峰，利用極化聚合物電光材料的折射率對導模吸收的影響來實現電光調制，並對器件的性能指標進行了實驗研究，同時利用製作的反射型電光調制器進行了視頻信號良好地傳輸實驗。 -
As a high band - efficiency digital modulation scheme, dvbc ( digital video broadcasting of cable ) qam ( quadrature amplitude modulation ) modulator is widely adopted in the wide - band communication area, such as hdtv broadcasting, cable modem, microwave communication, satellite communication and so on
正交幅度調制器（ qammodulator ）作為一種高頻譜利用率的數字調制方式，在高清晰度電視（ hdtv ）廣播、 cablemodem 、固定寬帶無線接入、衛星通信、數字微波傳輸等寬帶通信領域得到了廣泛應用。 -
In these versions the automatic management of pay signals ( encoded ) is included, the management is carried out by processing a signal coming from the video modulator for the transmitters or through the rf / if converter for the repeaters
在這些版本中，包括有給出信號的（信號編碼）自動管理，管理是通過處理信號來實現的，這信號是自針對發射機的視頻調節器來的，或是通過針對重復器的射頻/ if轉換器來的。
