Vector Difference with the AD531

The square-rooting properties of 3-variable analog multiplier-dividers, such as the AD531 and the 433, by the feedback solution of an implicit equation (e.g., the RMS circuit, page 13), have led to some interesting uses in vectorial combination. Vector sums were discussed at length in Dialogue, Vol. 6, Nos. 2 & 3. Read full article
