Time analysisEmpirical studies of human systems often involve recording multidimensional signals because the system components may require physical measurements (e.g., temperature, pressure, body movements and/or movements in the environment) and physiological measurements (e.g., electromyography or ...
instantaneous bandwidth, spectral kurtosis, and spectral entropy. Perform data-adaptive time-frequency analysis using empirical or variational mode decomposition and the Hilbert-Huang transform. Explore other time-frequency representations and analysis methods using the functions and apps provided by Wavelet ...
Complex vocalizations, such as human speech and birdsong, are characterized by their elaborate spectral and temporal structure. Because auditory neurons of... FE Theunissen,AJ Doupe - 《Journal of Neuroscience》 被引量: 319发表: 1998年 The Central Auditory System: A Functional Analysis Auditory neu...
Additionally, this method also provides a significant improvement of the overall classification performance when used in combination with some other (non-spectral) HRV features. 展开 关键词: Heart rate variability Resonant frequency Feature extraction Time frequency analysis Sleep Standards Bandwidth feature...
The authors address the problem of spectral analysis of signals with relatively wide linear phase modulation (PM), which is generated in differential measurement systems (i.e. bridges) equipped with parametric converters. It presents a wide (±2 rd) linear phase modulation scheme and puts forward...
