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?

(开关键控)载波正弦与一个单极binar和关闭正弦与一个单极二进制signal.OOK和关闭载体是相同的DSB - SC signal.Morse代码无线电传输度的单极二进制调制的,就是一个例子technique.OOK要使用的第一个调制技术之一,和之前模拟通信系统

加密 (交换) 的承运人窦打开和关闭与单极比单极的二进制信号载波有效值
