I made this schematic using Ni multisim and I got asked to find the ‘gain of this circuit using a 1v p-p 1kHz sine signal’ and I was unsure about this because I’m not sure if it means voltage gain or current gain. Anyways I put the desired signal in, but the waveform is the exact same as shown below and I don’t see some type of gain. I just need to know the gain of this circuit and whether this waveform is correct. Thanks in advance ~Neamus

    \$\begingroup\$ The emitter-follower (input to base, output at emitter, collector tied to some source) will have a voltage gain very close to 1 (but just slightly less.) It definitely can provide added current compliance, though. (But I don't imagine the question was about that. You are in a better position to guess on that.) \$\endgroup\$ – jonk Dec 28 '18 at 18:32
  • \$\begingroup\$ I'm not sure this and I'm not sure that Well, educate yourself and be sure. Even if you have a wrong opinion then I would respect you more than when you have no opinion. So you think this circuit has to have gain, why? What type of circuit is it? A common...? And do those have voltage gain? \$\endgroup\$ – Bimpelrekkie Dec 28 '18 at 21:56
