摘要: Noise is ubiquitous in electromagnetic measurements. can be very high frequency due to noise bursts or spherics, cultural present all but the most remote locations, and at lower frequencies magnetotelluric (MT) signal a source of active EM techniques. The successful suppression these different sources noise, whilst preserving signal, great importance recovering quality data as short time possible.
