Thanks Tom. But darn,I was kind of looking forward to the challenge of doing the Norton analysis. Now I prob will have to make myself do it. That's ok, thanks for your help. Have great day. Ray

Thanks again Dave. Funny how seeing various letters arranged a certain way on the screen (or page) can trigger memory pathways. As soon as I saw the impedance equations in your reply, I said to myself "Yep! that rings a bell". Now, I have a job to get the rest of the brain cells firing. Let's...

I vaguely recall using Norton theorem, with resistive circuits. I'll give it a whirl. Thanks for the pointer Dave. You are really challenging these old brain cells (its in there, but hasn't been accessed in 50 some years).

Well, if this is an intro to me: I am male, 63 years old, retired technical writer. Education is BS in Electrical Engineering Technology (not quite so much theory as EE, more practical stuff). Anyway, these days in between grandkids, doctor visits, and keeping everything working around the...

I have been trying to find out how the cutoff equation for the T section LC Lowpass filter is derived. I remember from college that f=1/(2pi√(LC)) for an LC circuit. But, with the T section, the cutoff frequency is given by f=1/(pi√(LC)), with L being the sum of the two inductors. My math has...
