As the signal is shifted from the original center frequency, the RF power analyzer reads lower and lower power levels as more and more of the signal shifts out of the intended transmission channel.
当信号从原中心频率偏移，信号越来越从设定的发射通道偏移，功率分析仪的功率电平会越来越低。
Results of absorption properties of different depth composites prove that the absorption peak is shifted to high frequency as the depth of materials decreases.
通过对不同厚度材料的吸波性能研究，结果表明随材料厚度的减小，材料对电磁波的吸收峰向高频移动。
Then, the echo is shifted by introducing a phase ramp in the frequency domain.
