求翻译:Of keying (switching) a carrier sinusoid on and off with a unipolar binar a carrier sinusoid on and off with a unipolar binary signal.OOK is identical to unipolar binary modulation on a DSB-SC signal.Morse code radio transmis-sion is an example of this technique.OOK was one of the first modulation techniques to be used是什么意思? 待解决
