Linearity

Because engineers talk in symbols instead of words...the following describes linearity.

  • A/*B = multiply by any complex number

<pre) x(t) --> system --> *A

                    |
                    + --> w(t)
                    |

y(t) --> system --> *B

x(t) --> *A

         |
         + --> system --> z(t)
         |

y(t) --> *B

</pre> If z(t) == w(t) then the system is linear.

In linearity, the values are scalable and follow the rules of superposition.

Basic linear algebra uncovers and clarifies very important geometry and algebra.
