Resumen:
The ability of the Maximum Entropy Spectral Estimate (MEM) to handle magnetotelluric signals was investigated.To this end simulations of naturally occurring signals and real data were spectral analyzed both by a standard FFTtechnique and by MEM. The method developed for the simulation of the time series, provides accurate amplitudes andphase, and turns out to be a good test procedure for spectral analysis methods, as they apply to MT signal processing.The final estimation of the apparent resistivity was better achieved by the FFT technique. Oscillations were observed inthe estimation of the apparent resistivities by MEM.
