For the emitter follower shown, with the given parameters below, determine the resistance looking into the base, the input resistance, the overall voltage gain, the overall voltage gain excluding the load, and the output resistance. For the small signal presented at the base, what is the amplitude of the output voltage? If the load resistance is changed to the two values below, what does the overall voltage gain become?
