Hi All
I have been trying to get to grips with opamp design using the attached 'tutorial'.
I never was very goos with equations so I am struggling. I am stuck on page 414.
Cheating (by using a spreadsheet) I can solve the simultaneous equation and get the correct values for the slope and intercept. However we now get to:
m = 10 = (Rf + Rg) ÷ Rg
This they have solved to be Rf = 9Rg
Can somebody please be kind enough to explain how this is reached.
Thanks in advance,
Rupert
