Summary:The instrument, described in the paper, represents a generalization of the low-frequency stochastic true RMS instrument. The generalization consists of replacing the input two-bit A/D flash converters with m-bit flash A/D converters, and replacing the two-bit multiplier-accumulator with an m-bit multiplier-accumulator. In this generalized case, the stochastic impact decreases, while the deterministic impact increases, causing the theory of operation to be more complicated. A complete theory of operation is also developed. Simulations strongly confirm this theory. It is shown that this generalization is equivalent, even in the case of a 5-bit instrument, to acceleration of, at least, 450 times over the instrument previously described.
