This inventive idea relates to the application of a modified\nWigner distribution as a tool for time-frequency signal analysis.\nThis method enables to evalute the signal structure simultaneously\nin the frequency domain and in the time domain. Thus the\nlimitations of methods working exclusively ...
<br/>Background-free pulsed microwave signal<br/>generation based on spectral shaping and<br/>frequency-to-time mapping<br/>Fangzheng Zhang, Xiaozhong Ge, and Shilong ..
Spectral analysis identifies localized sites of high-frequency activity during atrial fibrillation (AF).ObjectiveThis study sought to determine the effectiveness of using real-time dominant frequency (DF) mapping for radiofrequency ablation of maximal DF (DFmax) sites and elimination of left-to-right ...
2.5 Time-frequency representations The TF representations are tools mapping the time-domain signal to the 2-D TF domain [4,58,59]. They are designed to be concentrated around the IF [1,2,112]. For example, the Wigner distribution (WD) in the windowed (pseudo) discrete-time form is give...
Microwave photonic arbitrary waveform generation based on incoherent frequency-to-time-mapping (FTTM) accompanied by intersymbol interference, so called crossed FTTM (CFTTM). The pulse shape can be defined and tuned by properly adjusting the spectrum shaper (symbol shape) and the degree of intersymb...
The unknown frequency can be mapped to time interval between pulse appearances when scanning the modulated signal and the frequency-to-time mapping is established. In the experiments, we obtain a measurement range of 25 GHz with an error of ±510 MHz. Meanwhile, the measurement resolution for ...
