③锯齿波。锯齿波也是一种简单的波形,在PDP彩电中,锯齿波主要存在于电源电路中,例如,开关电源控制芯片一般外接有RC定时元件,定时电容C两端的波形就是一种锯齿波。④复合波形。复合波形是指没有一个固定形状的波形,这类波
③ sawtooth wave. Sawtooth is also a simple waveform. In the PDP TV, the sawtooth wave mainly exists in the power circuit. For example, the switching power supply control chip is externally connected with an RC timing component. The waveform at both ends of the timing capacitor C is a sawtooth wave. ④ composite waveform. Composite waveform is not a fixed shape of the waveform, this type of wave
