The quantification method is based on interpolating the signal spectrum about its 50/60Hz components to estimate the signal, and then the power line interference. Once these constituents are differentiated, a signal-to-60Hz-Noise ratio may be estimated and used as a quantifying metric. Simulations were used to compare estimation error introduced by two interpolation methods, one using the raw spectrum, and another using a smoothed spectrum. Results indicate that the smoothed spectrum method performs moderately better, but both can yield estimation errors &lt;10% relative to signal power.</p> ER -
