I know you have a rule requiring an attempt at the problem before posting here. The trouble is, I have a department required simulation project due this Wednesday and my professor is very behind in her lectures and has yet to even mention transient circuits.

I dont expect this problem to be done for me, but I would REALLY appreciate some tips or preliminary help in getting started.

I am tasked to:
Design a 1st-order circuit having a time constant of 1 ms. Simulate the output voltage for a square-wave input voltage. (Using Microcap to simulate)

This is all the info we are given...with this little of information, I am really at a loss on how to proceed.

Thanks in advance,

I presume you are talking about a 1st order filter. Is the filter to a high pass or a low pass filter?
Have you studied time constants yet? For instance, given a resistor and capacitor in a filter circuit, can you calculate the time constant.

Can you read ahead to get the information you need or can you ask the professor for help with the problem?

I quoted the assignment word for word, so you're guess is as good as mine.

We have not spent one second of class time on time dependent circuit functions. We've covered simplification techniques, node analysis, and amplifiers.

As for asking the professor, she is not very good at responding to emails, so I would have to wait to talk to her tomorrow at class...I would much rather start on it tonight though

any thoughts on how to proceed?

Help with Transient Circuits

Can you read ahead in your text? The rules in this forum are rather strict about giving help without some work by the student.
