Ghost hunters use EMF meters as an essential tool. According to the Anomolies Research Society, indicators of paranormal activity include fluctuations in EMF detection readings and background readings that drop or spike for no reason, with no explainable cause.

We’ll also look at how we can use Digital Signal Processing (DSP) techniques to improve our detector.
