42% . 9:69 PM Wed Apr 17 3)For the figure below assume the following specifications: VT-0.025 volts lco=1 mA GAIN 20 Vcxo 8 volts (VcEo does not equal Vco) Zin 10k VBE 0.7 volts Find the value of the resistors. (Hint: Using the specifications in the order given above you can find the resistors in the order Re, Re, Re, R and R) 4 For the amplifier shown below find Zin, Zout, and the GAIN-voin. Your answer will be in terms of R1, R2, R3, and R4. (Assume r. << R3 and β-e) Vee R3 N
