very low frequency receiver 甚低频接收机
ultra-low frequency receiver 特低频接收机
very low frequency electromagnetical receiver [地物] 甚低频电磁仪
low-frequency time-code receiver 低频时码接收机
Due to steady phase error, low-order PLL has a trouble in tracking frequency ramp signals, so that the receiver cannot lock carrier signals.
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。
In this curve, the point which had the largest inclined rate was a timing reference point of low frequency time-code receiver.
该曲线的斜率最大点即为低频时码接收机的秒定时参考点。
The experimental results show that the receiver has characteristics of ultra-low noise, high gain and good frequency response, which satisfies the requirements of the 3mmW LFMCW radar system.
实验结果表明，该接收机具有超低噪声、高增益和好的频率响应特性，可满足三毫米波LFMCW雷达系统应用的需要。
