Linearity

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

  • A/*B = multiply by any complex number
x(t) --> system --> *A 
                     |
                     + --> w(t)
                     |
y(t) --> system --> *B 

x(t) --> *A 
          |
          + --> system --> z(t)
          |
y(t) --> *B 

If z(t) == w(t) then the system is linear.

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