Ask about simulation using pspice

[newbie92]

Homework Statement

Simulate the circuit from 10Hz to 10MHz.
Produce the Bode Plot for the amplifier output (across RL).
From the Bode plot, determine the following:
i) Maximum gain, A(max)
ii) The cut-off frequency, fc.
iii) The frequency at the unity gain.

2. The attempt at a solution
the maximum gain and cut-off frequency i obtained from the graph,but what is the mean by frequency at the unity gain?

That should be the frequency where Vout = vs. That is, where the gain of the circuit drops to 1.

 

[newbie92]

then the answer is like the graph below?
when vout=vs=1v

I suppose that would be it (It's hard to make out the detailed contents of the image with its faint lines and lettering on a black background).
