WebApr 12, 2024 · The RMS or root-mean-square value is first squaring the values, then taking the mean and then neutralizing the squaring by taking the square root: R M S = x 1 2 + x 2 2 + x 3 2 + ⋯ n. Squaring a large value has much more impact than squaring a smaller value, so in the RMS value, the peaks will weigh much heavier than the bottoms and the RMS ...
