接收部分以超大规模AM/FM立体声收音集成芯片CXA1238S为主体，灵敏度、镜像抑制、信噪比等各项性能指标均达到设计要求；音频功率放大器采用集成芯片LM386，电压放大倍数最大为200。-Receive part of ultra-large-scale AM/FM stereo radio IC CXA1238S as the main body, sensitivity, image rejection, signal to noise ratio and other performanc

刚刚做的数字非线性功放的预失真模型，对调制信号的非线性功放造成的失真有很好的修复作用。-Just do digital predistortion model nonlinear amplifier, power amplifier nonlinear distortion caused by the modulation signal has a good repair.
