  Spike Detection and Processing of TDEM Signals using Wavelet Transform

  By Rajesh T. Keshwani, Vikas Teotia, Gopal Joshi, Sanjay Malhotra, Y K Taly

  Abstract: This paper presents a new method for spike detection, parameterization and processing in ground based Time Domain Electromagnetic (TDEM) signals. Time Domain Electromagnetic methods are used for mineral exploration by sub-surface conductivity measurement of Earth. The Earth’s response measured using inductive sensors are contaminated by spikes in form of sferics and due to load and phase shift in power distribution lines. The spikes present in the measured signal can significantly …
