The phase of the transfer function in Equation 3 at a given frequency can be calculated as. Equation 8. As can be seen, the phase of C(j ) has two parts: a constant phase of - /2 due to the pole at the origin, and a variable part as a function of frequency . The variable part is given by. Equation 9
