The power of the modulated carrier wave is increased by the rf power amplifier 射频功率放大器增加了调变载波的功率。
In communications , the amplitude variations of an amplitude modulated carrier wave 在通信技术中,调幅载波的幅度变化图。
The modulated carrier is also amplified , then applied to an antenna that converts the electrical signals to electromagnetic waves for radiation into space 调制后的负载电波也经过放大,然后加载到天线中,天线把电子信号转化成电磁信号,发射到空中。
