[PDF] Lecture 8 - Frequency Responses
To obtain the amplitude response, we take the absolute value of H(jω) To do this, we evaluate the magnitude of the numerator and the denominator separately To obtain the phase response, we take the arctan of the numerator, and subtract from it the arctan of the denominator

[PDF] Magnitude/Phase Representation - MIT OpenCourseWare
Thus, H(ejω) and ¿H(ejω) are commonly referred to as the gain and the phase shift of the system, respectively In magnitude and phase plots, as ω goes through a zero on the unit circle, the magnitude will go to zero and the phase will flip by π, as shown in the figure below
