An input voltage of 2 V rms (measured from base to ground) is applied to the circuit

Question:

An input voltage of 2 V rms (measured from base to ground) is applied to the circuit of Fig. 3.21. Assuming that the emitter voltage follows the base voltage exactly and that Vbe (rms) = 0.1 V, calculate the circuit voltage amplification (Av = Vo/Vi) and emitter current for RE = 1 kΩ.
