Use this tag if the question you are asking is an assignment or homework with which you require assistance. EE.SE is not a homework answering service, so make sure you show what you have attempted so far and are specific as to where you have gotten stuck.
Homework/Assignments are quite common on Electronics courses and generally involve some circuit analysis and design.
Such questions are not off-topic on EE.SE, and so long as you are clear from the off that your question is homework related, your honesty will be rewarded with hints and tips if you are stuck solving your assignment.
However, be aware that EE.SE is not a homework answering service, and we are not here to do your work for you. If you do not show any attempt to solve the question, your question will more than likely not be received well, attract downvotes, and probably be closed.
