4. Transfer function. Complex frequency response

4.1 Transfer function

If we consider an input signal f (t ) = f0 exp (pt ), where p denotes a complex variable (p = a + j ω, a > 0), and the linear system response y (t ) = y0 exp (pt ), we call the system transfer function the ratio :T (p)=Y (p)F (p)

with :

F (p ) and Y (p )
 : 
Laplace transforms of f (t ) and y (t )
