摘要
本文根据对平滑调频信号相位路径的要求，分析了预调滤波器应具有的特性，介绍了实现TFM调制的工作原理，并设计了用正交调制法实现TFM调制的电路框图，并给出了TFM信号的频谱特性。
According to the requirement of the Tamed Frequency Modulation (TFM)signal phase path,the required properties of the premodulation filter are analyzed, the working principle of TFM modulation is illustrated and the circuit diagram of TFM modulation is designed by means of orthogonal modulation realized method, and the spectrum property of TFM signal is offered as well.
