    Bandpass Transformation: equation

    Hello everyone is struggling with the book Microstrip Filters
    for RF / Microwave, also associated with the book Microwave Engineering. I am following the bandpass filter formulas. I am encountering much less difficulty following what is in the book. Through my studies I realized that the excerpt from the exercise works, using another type of table being that nothing is mentioned in your description of the book that has to use this table. Even so when I go to the second step of the same exercise there are errors and I made some maneuvers to get to the exercise, but I have no idea what I should do and what to follow. Who can explain to me make a resolution of the exercise and say where it is wrong, because it makes no sense to me. Even following the book step by step I think something is wrong.
    I will send in the appendices my resolution of the calculations. And the supposed table being that I think is the right one for me.
    The PDF of the resolution is on pages 9 to 13.Click image for larger version.

    Re: Bandpass Transformation: equation

    Because the Tables are not corresponding each other..One shows Equal Ripple type Filter while the other is showing Butterworth Approximations..
    They are not same filters..
