| 摘 要： | 针对文献［１］提出的多次采样方法，证明了多次采样法在一定条件下等效于一种希尔伯特变换器，并用数据证明：当信号的相对带宽小于８０％时，９次采样所获得的正交分量误差可忽略。

| Abstract: | The multi order sampling method is suggested considering the error for second order sampling method.It is proved that the multi order sampling is equivalent to one Hilbert transformer under certain conditions.It is testified that the error in the quadrature component obtained by the ninth order sampling can be neglected when the relative bandwidth of a bandpass signal is less than 80%. |
