Figure 4From: Evaluation of waveform data processing in Wave-Particle Interaction AnalyzerWave amplitudes and phase differences. (a) Amplitudes of the model chorus waves. Waveform to which passband filtering is applied (red). The original waveform is plotted for comparison (black). The dots indicate the sampling data points. The FFT frames are shown at the top. (b) The instantaneous phase differences of the waveforms in (a).Back to article page
