6. Augment your Matlab code to use Eqs. 5 8 to calculate and plot the four impedance matrix parameters of your II-circuit as a function of frequency (again over the 10 KHz to 400 MHz frequency range). The four plots should display the real and imaginary parts of each parameter, in Ohms. To demonstrate the type of plot that you should be generating, Fig. 8 depicts a plot of one of my measured Z1 results.
