Designing filters using fourier series


I did an EE degree several years ago now, and obviously covered things
such as fourier series and filter design. What I never covered was how
to get component values from the fourier seires.

Can anyone recommned either some online resource or a book that I can
buy? I've had a rumage through the IEEE archieves and obviously a
google seach but cant find a few basic examples to get me going

Thanks in advance

I am not exactly sure it has what you want, but a great book for
understanding more complex filters and going from the math to real world
applications is
"Theory and Design of Active Filters", by L.P. Huelsman.
I have not cracked mine for a few years though so I don't remember what
all it had. I originally bought it to better understand GIC filters back
in the days before delta sigma D/As for audio when you needed steep
filters on audio (as in mid 1990s).

For basic understanding of 1-7 pole butterworth, chebychev, bessel and
how to make them in the real world TI has a great app note and free
software. It is old Burr Brown stuff they converted to Windowz. Much
more basic than the book I recommended.
