Matti, please:

1. Get Rick Lyons' book: Understanding Digital Signal Processing

Your question stream show that you're actively avoiding to learn
the basics. It will get you nowhere. I do know that we Finns are
stubborn, but too much is too much also here.

2. Do not change your sender ID all the time.

A description on creating arbitrary magnitude response filter using iFFT is given.

There it's also said that:

"The next step is to take the Inverse DFT to move the filter into the time domain. The quickest way to do this is to convert the frequency domain to rectangular form, and then use the Inverse FFT."

What does it mean to convert the frequency domain to rectangular form?
