No, interview questions for undergraduatehi Ben,
Is this a College assignment.?

Well you've named them properly. What's keeping you from solving them? Start with the definitions of how (ideal) resistors, inductors and capacitors behave. For instance ohms law, V = I•R defines the behavior of a resistor. The other two are a little trickier but it's all math.No, interview questions for undergraduate

ok, thank you.No, interview questions for undergraduate

Moved to Analog & Mixed Signal Design
Is this output all right?
The general shape is ok but it shouldn’t trail off at the end. And although the axes of the input wave are not labeled, I’d probably label mine. I’d also note major features such as the halfway point and such.Is this output all right?
Can you figure out the equations for the outputs in each case in terms of the circuit parameters?

1 RCL circuitCheck the units on your final equation. They don't work out. It's not the only place you made that mistake, either.
Keep in mind that (dVo/dt)² is NOT the same as dV²/dt². The former is the square of the first derivative and the latter is the second derivative.
Once you have fixed that, then solve for the output voltage in terms of time and the circuit parameters. Then plot them on a reasonable set of axes.
Exactly. If you've worked enough of these problems, you can draw the plots and note the major features almost from rote.A question like this is looking for bigpicture concepts, not detailed minutiae.
Your guys makes me confused. What shoud I answer it? My awnsers are right? What concept shoud I answer? This is the part your guys can help me with. According to your statements, how do i answer them in 2 minutes? What is key concept?Put yourself in the interviewer's place. If you gave someone what you posted in the first post, what would you like to see them able to do within the limited time and resources of an interview.
I would expect someone to be able to answer all three reasonably well in less than two minutes.

I know how to do those math, but what does an interviewer really want me to answer them? Please help me. Thank you. They don't need me to solve them. They want me to describe the output for those questions.Exactly. If you've worked enough of these problems, you can draw the plots and note the major features almost from rote.
It's been a long time since I solved these classics but the math above doesn't look even vaguely familiar to me.
Take a shot at it and then let us provide feedback on YOUR answer.Your guys makes me confused. What shoud I answer it? My awnsers are right? What concept shoud I answer? This is the part your guys can help me with. According to your statements, how do i answer them in 2 minutes? What is key concept?
