限带信号 [xiàn dài xìn hào]
[电子] band-limited signal
- 本文提出了一种离散带限信号通过线性系统后的外推算法。
In this paper we present an extrapolation restoration algorithm for discrete band-limited signal blurred by linear system. - 可变载频带限信号的重采样，一般归结为按转换比P/Q（P为内插比，Q为抽取比）对原采样序列做内插和抽取。
The resampling of the passband signal with variable frequency is likely implemented by interpolating and decimating the original sequence according to the converting ratio (P/Q). - 一维带限信号的重构与外推作为一个典型的不适定问题，在傅立叶分析、谱估计和图像恢复中有着广泛的应用，对此已有一些学者做了大量的研究工作。
The extrapolation of one-dimensional band-limited signal, as a typical ill-posed problem, has a variety of interesting applications in Fourier analysis, spectral estimation and image restoration.
