Question

Please, help me to solve the first three branches (a, b, and c)

The amplifier circuit below has a single ac input and two ac outputs. Assuming transistor
parameters of ß= 200 and VBE = 0.7 V:
(2-a) Determine the Q point.
(2-b) Is the transistor in the active region? Explain thoroughly.
(2-c) Construct the T-model of the transistor with all parameters labelled and evaluated.
Assume room temperature.
(2-d) Draw a complete small signal circuit model, then find the voltage gain for both outputs.
(2-e) Based on the analysis results, what is the function of this circuit? Suggest a proper
application.
(2-f)
Use Multisim to verify all of your results. Compare and comment.
(2-g) Assuming that each output is feeding a 100-k2 resistor, determine the total voltage gain
and current gain for both outputs. Also, calculate the amplifier input resistance and the
amplifier output resistances.
