gaussian filter design - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

I'm working on modelling a system that include a gaussian low pass filter on litterature on the net i can find information about the waveform of the filter but i can't find nothing about the formulas to determine the L,C and R values. Does someone can help me or knows a website with this information ?

If you need a design of a filter, there is a program on the website: called ELSIE. You can put in your parameters ( stop band, passband etc) and it will spit out the values for the filter.

Greetings RF-Ban:

After reading of your need for the Gaussian prototype values, I did a search for them and could not locate tables for the Gaussian filter. So, I used a filter design program and set the frequency for 1/(2*pi) and the source/load terminations for 1 ohm and came up with a table of values for order 3 through 10. If you still need them, you can find them here: ... values.htm

While I was at it, I updated the Chebyshev tables to include even-order filter values. A lot of tables only supply odd-order values, because the insertion loss of a Chebyshev at DC (0 Hz) is equal to the ripple value rather than 0 dB.
