AM无线电接收机噪声消隐信号发生器包括收到一个适应的产品检测中频信号调制的音频信号和同步检测AF信号，第一个低通滤波器，适应从产品检测筛选的电压指示的平均中频信号强度，第二个低通滤波器适应来自AF信号电压和参考电压产生电路ratiometrically通过一个共同的直流电源，有效地生成一个参考电压大致等于过滤相关产品检测产品检测电压的中频信号的情况下。包括一对跨越的第一和第二低通滤波器的输出串联电阻分压器电阻交界的输出，这种比例的电阻来产生，当音频信号等于一个预定的调制参考水平的中频信号强度，在分压器的输出，一个比较有效的的电压等于参考电压比较与参考电压分压器的输出电压，并产生噪音消隐信号时，
