| 摘 要： | 本文报道了一类非带限信号恢复的一种方法。对非带限信号f(t),若存在可逆函数g(t),使gf(t)]带限,其最高频率为ω_0,则f(t)可以从大于2ω_0采样率的采样数据准确重建。计算结果与本文建立的理论符合得很好。

| Abstract: | A method for a kind nonband-limited signal restoration is presented here. For a nonband-limited signal,f(t),say,if there exists a reversible function g(t) satisfying that g(f(t)] is band-limited and the highest frequency is w_0 ,then f(t) can de precisely higher than 2w_0. Computationis is consistent with the developed theory perfectly. |
