利用正反馈从输入信号中取得波形合成形式参考源的检测器,能够对包括单边带和双边带波(无载波)在内的各种传输形式进行解调。在单边带传输中,该检测器能够检测弱信号而没有来自参考振荡器的杂散噪声问题,而且还能对脉冲型噪声显示一种特有的变化率限制作用。在双边带波(有或没有载波)传输中,它充分利用了信号频带两个部分的边带能量,有效地抑制了脉冲型干扰。在任何一种具有相关上下边带的调幅传输中,它大大地消除了与选择性衰落交织在一起的失真。
The use of positive feedback from the input signal obtained from the waveform synthesis of the reference source detector, including single-sideband and double sideband (no carrier), including a variety of transmission formats to be demodulated. In single-sideband transmission, the detector can detect weak signals without spurious noise from the reference oscillator and can exhibit a unique rate-of-change limit for impulsive noise. In the bilateral band (with or without carrier) transmission, it makes full use of the signal band of two parts of the sideband energy, effectively suppressing the pulse-shaped interference. In any type of AM transmission with associated upper and lower sidebands, it greatly eliminates the distortion that is intertwined with selective fading.
