Abstract
We apply wavelet spectrum and bispectrum techniques to study nonstationary plasma edge turbulence. We examine floating potential fluctuations and polo idal magnetic field oscillations measured in the tokamak TBR plasma perturb ed or not by resonances created by external magnetic fields. Our analyses s how evidences of intermittent linens and nonlinear correlations between the se two kinds of oscillations.
