专利汇可以提供Distortion compensated electromagnetic wave circuits专利检索，专利查询，专利分析的服务。并且This application described predistortion and postdistortion compensation arrangements wherein compensation is restricted to the nonlinear portion of the transfer characteristic of the network to be linearized. Accordingly, the compensating signal components employed correspond solely to the distortion components of the transfer characteristic. To avoid dispersion effects, the dynamic characteristics of the compensating networks and the network to be linearized are substantially independent of time.，下面是Distortion compensated electromagnetic wave circuits专利的具体信息内容。
