载波信号
[通信] carrier signal
- 所以射频载波信号即可由System 40主机中的同轴继电器进行路由。
Therefore, the RF carrier signal is routed by coaxial relays in the System 40 chassis. - 低阶锁相环跟踪频率斜升信号时产生的稳态相差致使环路失锁，接收机无法锁定载波信号。
Due to steady phase error, low-order PLL has a trouble in tracking frequency ramp signals, so that the receiver cannot lock carrier signals. - 讨论了载波信号的注入、提取以及包含转子位置信息的高频负序电流的外差处理技术。
The carrier signal injection method and the heterodyning algorithm for the extraction of high frequency current containing rotor space-position information are all discussed.
