%X the noise effect in determining the temporal parameters in lightning electrical field signals are analyzed using wavelet transforms for noise reduction. signals recorded in bogot¨¢-colombia which were affected by noise from the analog-to-digital converter, from the electronic circuito and from environmental noise were used. by using a wavelet based noise reduction procedure, electric field signals were processed and the level of noise in these signals was reduced. the effectiveness of the propssed technique was demonstrated by analyzing the main parameters of electric field signals, obtaining deviations up to 84% when parameters of the original signals were compared with the ones of the procesed signals. in conclusion, the wavelet transform represento an appropriate technique for reducing the noise of lightning electric field signals.
