The-Fourier-transform
- 将时域信号分解为不同频率的正弦信号或余弦函数叠加之和。连续情况下要求原始信号在一个周期内满足绝对可积条件。-The time-domain signal into different frequency sine or cosine function signal superimposed sum. Required to meet the continuous case the original signal is absolutely integrable conditions in a s
spectrum-estimation
- 功率谱估计是利用有限长的数据估计信号的功率谱,广泛应用于各个领域。功率谱估计主要分为经典谱估计与现代谱估计。常用的经典谱估计方法有周期图法,相关法,周期图的改进法,常用的现代谱估计方法有最大熵谱估计,AR模型,MA模型,ARMA模型。经典谱估计适用于长序列的信号,其主要缺陷是描述功率谱波动的数字特征方差性能差,频率分辨率低,现代谱估计适用于短序列的信号,旨在改善谱估计的分辨率,并将其应用于实际地震资料的谱分析。 -Power spectrum estimation is the use of
