Hello, I'm currently studying for an exam and came across a question I cant seem to figure out. How exactly do we go about calculating the phase of a frequency response. Here is the question, it for part A) iii. Here are the answers to the other parts and the sketch of the magnitude: I know you have to add the phases of the H1(w) and H2(w) to get the overall phase but I cant seem to figure out how to get the phase of each one. Any help is appreciated thanks.
