Hello, I am trying to work out the resistor values for an 'O' attenuator.
I am using the attached formula to work out resistor 3's value.
My values to insert into this formula are:
Input impedance (Z1) = 50 Ohm
Load impedance (Z2) = 600 Ohm
a =1.995
However when I substitute these figures I am getting a negative number result.
Is this correct ? I mean if you get a negative result, do you just make it positive and use that for your resistor value ?
Thanks for any help.
