jjw,

I doubt if the OP will return. I didn't get the reported correct answer two ways ...
excel doing the math or just an ac analysis from my simulation program. However, the excel spreadsheet agreed with the simulation.

Seems a bit premature. What makes you think the OP won't return. They've posted five messages in this thread today. Looking at the timestamps it seems very likely that they are in a part of the world where they might be asleep right now. Let's see if they return in the next day or so.

 

True ... I would be happy to be proven wrong with that assessment.

 

Don't post your answers yet.
I got an idea what is happening here

 

3dB point is at 1/sqrt(2) ~ 0.707

hi jjw,
Thanks but I do know this.

I was trying to give the OP a hint to look at the divider ratio's, solving using the transfer function method.

Had I told him the ratio was 0.707, I would have virtually given him the answer, which I will not do for a homework question.

For home work, I think we should be shown the OP's attempt at answering the questions. I only give hints and clues hoping it will point the OP in the right direction.

Ok, i knew you know it
