B Frequency Response Modeling Frequency response modeling of a linear system is based on the premise that the dynamics of a linear system can be recovered from a knowledge of how the system responds to sinusoidal inputs. (This will be made mathematically precise in Theorem 13.) In other words, to determine (or iden- tify) a linear system, all one has to do is observe how the system reacts to sinusoidal...

doing something wrong with the units because I'm getting over 50%
error?)

For k = 2 N/m, m = 20 g, and c = 0.03 N-s/m, calculate and plot
the magnitude (in m/N) and phase (in degrees) of the frequency
response function from the excitation f(t) to the response x(t).
Show your plots over a frequency range of 0 Hz to 3 Hz, which
should include the resonance peak (be sure to check units).
