Circuit analysis homework help!

[AznMaverick]

we have to find the network functions of these circuits, then graph (in matlab) the magnitude and phase shifts of the circuits. HELP ME!

thanks!

Dude, you were getting a Ph.D. in Electrical Engineering in 2002... What happened to that? 🙂

Sorry, I don't like circuit analysis

that's my professor 🙂

thanks!

dude...just do KCL or KVL.../=P

A) get a study group
B) Talk to the TAs
C) Talk to the professor


I passed that class for a reason.. to never do that stuff again :disgust:

not even KVL or KCL... voltage divider in the complex domain.... PHASORS baby!

hahaha yeah...i didn't even look at the circuit...i thought it was some complex blob of mass! 🙂

phasors..mmm..mmm....good!

actually i did use voltage division, and came out with weird answers with a w(frequency) that i'm not sure what to do with.

damn, of all my EE classes, circuit analysis is the HARDEST. and it sucks to know that i have to actually know this stuff like the back of my hand.

yeah...but sadly you'll have to know some of this stuff for other classes...so if you learn it now you'll save yourself the heartache!

More Phasor goodness 🙂

well... post your the transfer function that you got (vout/vin). Then you can use matlab (although I don't see why you have to be that complicated), and sweep the value of w from something small to something large. Plot the magnitude and phase....

thanks, helped a lot! also BruinEd03 with the complex #s
