Set up the circuit in the pspice program. Use J2N3819 as JFET. Find entry and exit signs for 2 periods of time with the help of "transient" analysis. VIN = 200mV (pk − pk), f = 1kHz
RIN = 1kohm, RS = 1.2kohm, C1 = 5.6μF, C2 = 5.6μF, VDD = 18V
a- Draw the input and output sign when RD = 3.3kohm and RL = 4.7kohm.
b- Draw the input and output sign when RD = 1kohm and RL = 4.7kohm.

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?
