Comprehensive filter design reference?

[bitrex]

In most of the EE textbooks I have, the topic of filter design seems to essentially be treated like "Here are some active filter topologies, and here are their normalized transfer functions, and here are a lot of tables of pole locations for say the 4 pole 1 dB Chebyshev filter. See you later." I'm wondering if anyone knows any good references, online or dead tree format, that I could use to get some insight into why the pole locations are what they are for certain filter responses?

There is a lot of info out there. Just Google "electronic filters" or "Active filters". There are some good chip manufactures application notes that might help like this one: http://www.national.com/an/AN/AN-779.pdf"

I completely understand your frustration with the lack of comprehensive information on filter design in most EE textbooks. The topic of filter design is a complex and multidisciplinary field, and it requires a deep understanding of various concepts such as circuit theory, signal processing, and control theory.

To gain a better understanding of the pole locations and their relation to filter responses, I would recommend looking into advanced textbooks on filter design, such as "Active Filter Design Techniques" by C. G. Sodini and "Active Filter Design Handbook" by T. H. Lee. These textbooks provide a more in-depth analysis of filter design principles and offer a comprehensive reference for understanding the relationship between pole locations and filter responses.

In addition to textbooks, there are also various online resources that can provide valuable insights into filter design. Websites such as All About Circuits and Analog Devices offer comprehensive tutorials and articles on various filter design techniques and their applications.

Lastly, attending conferences and workshops on filter design can also be beneficial in gaining a deeper understanding of the subject and connecting with experts in the field. I hope these suggestions help you in your pursuit of a comprehensive filter design reference.
