| 7. | The author thought that the high frequency components were included in the input signal originally . after having crossed the forbidden region , they have not been decayed but the main frequencies in the input signal have been decayed enormously
分析表明，输出信号的高频成分系输入信号本身所具有的，在通过截止区后未被衰减同时主频却发生了非常大的衰减而显现出来。 |
