载波正负半周分别调幅的理论设想

这是一种理论上的设想：用两个不同的低频信号（调制信号）对一个高频载波信号（被调制信号）的正负半周分别调幅，即用一个低频信号对载波信号的正半周调幅，另一个低频信号对载波信号的负半周调幅，以实现一个调幅载波传递两路信号的目的，从而在很大程度上缓解通讯、广播、电视通道拥挤问题，并使一些信号传递技术更为简单。

A Theoretical Assumption of Septarating the Positive Semicircle AM from the Negative One AM of Carrier Wave

This is a theoretical assumption that two different low frequency signals (i.e. modulating signals)are applied to separating the positive semicircle amplitude modulation(AM)from the negative one AM of one high frequency carrier wave signal (i.e.modulated signals),namely,one low frequency signal is applied to the positive semicircle AM of carrier wave signal,while another low frequency signal to the negative semicircle AM of carrier wave signal so as to achieve the goal that one AM carrier wave can convey two signals.Thus,the crowded or busy passages of communication,radio and television can be alleviated to a great extent,and some signal conveying technology may be made much simpler.
