摘要
在连续信号离散过程中,由于取样器固有噪声及取样脉冲抖动等因素的影响,取样信号被噪声污染。本文讨论含噪声取样信号频谱误差的估计问题,给出估计频谱误差上限及下限公式。所得结果对取样信号和系统质量的估计有参考价值。
The sampled signal is often corrupted due to intrinsic noise in sampler and time jitter of sampling pulse when the continuous signal is in discretization. The evaluation of spectral errors and their bounds for sampled signal are discussed in this paper. The obtained results are useful for estimation of sampled signal and system quality.
