carrier frequency signal transmission

基本解釋

The former realizes steady transmission of signal by testing and analysing the carrier channel's frequency characteristic .
前者是通過(guò)對(duì)載波信道的頻率特性時(shí)變性測(cè)試、分析，實(shí)現(xiàn)信號(hào)平穩(wěn)傳輸。
Analog modulation carrier signal amplitude, frequency, or phase change with the analog input signal to the pre transmission and corresponding occurrence change modulation method.
