Linearity 2


Linearity 2 : In mathematics, a function F is linear if F(ax) = aF(x), and F(x+y) = F(x) + F(y), where x and y are variables and a is a constant. A system is linear if its output can be expressed as the convolution of the input and the impulse response. When the input is a function of time in a linear system, the output can be obtained from using its frequency response alone. See convolution and frequency response. See Section 5.7 of Chapter 5 in this manual and Wielandt (2002, p. 297) for testing the linearity of seismometer
