Abstract: The difference between the property of singularity of a signal and that of noise under the dyadic wavelet transform is revealed. Due to this merit,the experimental data of the interior electric and magnetic intensity of a concrete building radiated by a electromagnetic pulse are processed by singularity detection and denoising.

Key words: wavelet transform, singularity defection, EMP, denoise
