Load modulate technology based on sub - carrier wave for fuze setting information feedback 基于副载波的负载调制技术实现引信感应装定信息反馈的方法
Technical specification for nicam - 728 digital audio signal transmission with satellite tv channel subcarrrier Nicam - 728卫星电视信道副载波传送数字声技术规范
Based on the theory of dpll , line phase locked and color subcarrier regeneration were designed 依据数字锁相环的基本原理,完成了行锁相、色副载波还原电路的设计。
Hfc applies the sub - carrier fdm technology , with video , data and voice signals simultaneously transmitted on the coaxial cable via the modem Hfc采用副载波频分复用方式，各种图像、数据和语音信号通过调制解调器同时在同轴电缆上传输。
Considering the effect of line phase locked , a front modulation is added in color subcarrier regeneration hardware module to improve the module ’ s precision 考虑到行锁相对色副载波还原的影响,在硬件实现时增加了前向调节的功能,提高了色副载波还原的精度。
