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 ...
tfcohf: Function to compute time-frequency coherence between a pair of continuous signals. The cross and auto spectra are smoothed to estimate time-frequency coherence.

Time-Frequency analysis using Bayesian Regularized Neural Network ModelDuring the last twenty years there has been spectacular growth in the volume of research on studying and processing the signals with time–dependant spectral content. For such signals we need techniques that can show the va...
Synonyms Spectrotemporal analysis Definition The term time-frequency analysis summarizes analysis techniques that quantify the temporal evolution of spectral properties of signals. These techniques provide powerful means to study the dynamics of rhythmic phenomena, which are of great relevance in neuroscience...

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...
The spectrogram is a basic tool in audio spectral analysis and other applications. It has been used extensively in speech analysis [56]. The spectrogram can be defined as an intensity plot (usually on a log scale, such as dB) of the Short-Time Fourier Transform (STFT) magnitude.8.4 As ...
