"WebThe transfer function is defined by Vout=T (jω)×Vin with V in = V in e jωt. Sometimes, we can note p or s=jω which is known as the Laplace variable. From this transfer function, two important parameters can be computed. The first one is the gain/amplitude (G), which is found by taking the norm of this complex function: G= T (jω) .
