Frequency responce in a common base amplifier

[kpstp88]

How the voltage gain of the amplifier depends on the frequency of ac signal. please explain.

what is the role of coupling capacitors?

how voltage gain is effected in mid , high and low frequency range?
thanks.

You must show your work before we can offer any tutorial help. Read the Rules link at the top of the page.

If you are an absolute beginner, I recommend you to google these terms. If you, again, need help then you must show your effort and want people to help you... as Berkeman said.

The first and third questions are related to your general understanding of small signal voltage gain of an amplifier. To start you off, what do you understand about the mid-band AC gain of an amplifier? How should you treat capacitors at high and low frequency ranges?
