Use the graphical construction approach to construct the asymptotes of the impedances Z1(s) (the impedance between vin and the op amp inverting input), and Z2(s) (the impedance between the op amp inverting input and the output). Sketch these asymp- totes to scale on semilog axes, and label each asymptote with the corresponding circuit element impedance magnitude.

In a unit cell of fcc structure, indicate the position of one of the tetrahedral interstitial sites by plotting the corresponding tetrahedron. do the same for one of the octahedral interstitial sites (in a separate fcc unit cell). mark the positions of all the tetrahedral and octahedral interstitial sites in the unit cells. how many equivalent tetrahedral sites and how many equivalent octahedral sites are contained in a fcc unit cell, respectively. what is the coordination number for a tetrahedral site and what is the coordination number for an octahedral site?
