As it can be seen the voltagespectrum of the 800v quasi resonant flyback is higher at frequencies below 1 MHz, and is getting lower above 1 MHz compared to both 600v designs.
As in case of drain-source voltage this method allows to associate the elements of the drain current waveform with its contribution to the whole spectrum.
就象漏源极电压的例子那样，用这种方法也可以找出漏极电流的哪一部分对电磁干扰频谱产生影响。

The effect of the incident light spectrum and the waveguide electrode's DC bias voltage on the modulation sensitivity is discussed.
