spectra raw data

In this folder the Power Specral Density of the recorded signals is available together with its complementary metadata in the same excel file. Several excel files allow to distinguish relevant parameters (material, location, presence of intra-arterial pressure probe) as well as relatively less relevant ones, e.g. how many times (runs) the measurement was taken or similar.本文件夹中，记录信号的功率谱密度（Power Spectral Density）与其补充元数据均存储于同一Excel文件内。多个Excel文件可用于区分核心参数（包括材料、采集位置、是否存在动脉内压力探针）与相对次要的参数，例如测量轮次（runs）的数量或其他类似信息。
