Last month, we saw how you can use vectors to define complex circuits and determine current. This month, we'll show you how to use vector diagrams and some simple math to calculate neutral currents in ...

If \(\overrightarrow {PQ} = \left( {\begin{array}{*{20}{c}} a\\ b\\ c \end{array}} \right)\) then the magnitude of \(\overrightarrow {PQ}\) is written as \(\left ...

The quadrature processing techniques employed in spectrum analysis,computer graphics, and digital communications routinely require highspeed determination of the magnitude of a complex number (vector ...
