When adding vector quantities remember that the directions have to be taken into account. The result of adding vectors together is called the resultant. In problems, vectors may be added together by ...

Subtracting a vector is the same as adding a negative version of the vector (remember that making a vector negative means reversing its direction). \(\left( \begin{array}{l} a\\ b \end{array} \right) ...

Digital or vector modulation can provide increased spectral efficiency, higher data security, and higher quality communications. This comes at a cost of increased system complexity and a resultant ...
