摘要: The edge turbulence in the ADITYA tokamak [Phys. Rev. Lett. 69, 1375 (1992)] is examined using wavelet analysis techniques. filters are used to separate low and high frequency components. filtered plasma density floating potential fluctuations show leptokurtic non‐Gaussianity (kurtosis, K≳3) at frequencies, whereas, components nearly Gaussian. recently developed bicoherence technique Plasmas 2, 3017 (1995)] extended Mexican hat wavelet. When data technique, it found that turbulent signals exhibit episodes of quadratic interaction which coupled.
