2. If the input and output of the above amplifier are capacitively coupled through 0.1 F capacitors, (i) analytically determine the lower 3 dB frequency; (ii) Simulate and verify; (iii) What is the upper 3 dB frequency?; (iv) In your simulation model, what are the parasitic capacitances of the BC547 you have used ? (v) Using those values of Cr, Cu and CCE, analytically determine the upper f3dB.
