c) If in figure 3.1 a npn BJT transistor with a current gain ß = 75 is used and RB1 = 100 kohm, RB2 = (10 x 1.XY) kohm, Rc = 7.5 kohm, RE = (1.XY) kohm and Vcc= 24 V determine the Q-point (values of VBE, IB, VCE, IC). d) Now sketch the ac circuit model of the amplifier shown in figure 3.1. Using the Q-point determined in Q3 (c) calculate the value of the ac open circuit voltage gain Av and the ac short circuit current gain Ai. (Assume that Vth = 26 mV). What role do the capacitors Cin and Cout play in the operation/use of this ac amplifier?
