Homework Statement



Our professor makes us design our own lab. For the lab we have unknown resistors, capacitors and inductors. Using an oscilloscope, function generator and some wires we have to figure out what the values are for all these elements.


Homework Equations





The Attempt at a Solution



I figured that we would be able to get a damping sinusoidal graph, plot some equation to the peaks and get some numbers from that, but we just are not getting those types of graph using a square sine wave. I'm thinking that there is something we can do with phase shift using a sine wave. I've already spend more time than I have trying to figure out what to do and am still not sure. I'm just looking for some ideas on what approach to take towards this lab.

If you take the components two at a time (RL, RC, LC), what circuit configurations can you construct from the pairs for which you know the properties? (Think time constants, resonances)

What are the expressions for those properties? How might you measure those properties with an oscilloscope and function (frequency) generator?
