脉宽调制发射机,在高调幅时,有调幅波包络线先平峰谷后冒尖的现象。对于这个问题所带来的后果,本刊曾发表过如下观点:串馈脉宽调制发射机“梯调前的最大边带波输出功率比理论值的差距较大,扣除载波跌落后还差20%左右”,我们对此有不同看法。
Pulse width modulation transmitter, in the high-amplitude, amplitude wave envelope Xianfeng peak after the tip of the phenomenon. For the consequences of this issue, we have published the following observations: Serial pulse width modulation transmitter “ladder before the largest sideband output power than the theoretical value of the larger, after subtracting the carrier is still 20 after the drop % Or so ”, we have different views on this.
