恢复信号所需的已知采样点数占信号总长度的比例Ｐ与采样频率有关，在一定条件 下，提高采样频率，可使Ｐ远小于三分之一。已知的采样点可不限于从信号的第一点开 始，也不限于是一段连续的采样点。本文的研究结果扩大了信号重构方法的应用范围。 试验例子的计算机计算结果与理论分析相符。
The ratio of the known sampling points required to recover the signal to the total signal length P is related to the sampling frequency. Under certain conditions, increasing the sampling frequency can make P far less than one-third. Known sampling points may not be limited to starting from the first point of the signal nor to a continuous sampling point. The results of this paper extend the scope of application of signal reconstruction methods. The experimental results of computer calculation are consistent with the theoretical analysis.
