Abstract :
The instrument, described in the paper, represents a generalization of the low frequency stochastic true RMS instrument given in (1999). 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 deterministics impact increases, causing the theory of operation to be more complicated then originally assumed. 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 described in (1999)
