    Hello ALl

    To be able to get the equation for 3.56 on page
    http://www.geocities.com/jason_class/circuit_Zs.jpg
    (pls save and open in picture viewer),
    I use the result for equation Z1= (1/(a+1)^2).Z2 (page 3, 4th equation
    after Figure 5) from document at page
    http://www.coilcraft.com/pdf/doc157.pdf

    However, I found that from the .pdf file, the 1st and 3rd equation are
    contradicting with their results.

    Then I found that 4th equation is different when I derived from 1st
    equation after Figure 5.
    I found that it is Z1= (a+1)^2).Z2 which contradicts with the one shown
    in the pdf file.
    If I am right with my derivation, then I cannot apply and get the right
    Zs' impedance for the page on
    http://www.geocities.com/jason_class/circuit_Zs.jpg which I found from
    book.

    Kindly let me know which is correct and eventually how to get Zs'?
    Thank you so much
    please help

    rgds and thanks

    The 1st equation after figure 5 is wrong. It should be:

    V1/V2 = N2 / (N1+N2)

    Hi Andrew

    Thank you so much for putting time in to clarify for me.
    I will check it out , I think somewhere still I need some deep thinking
    to sort.
