RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

gaussian filter design - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. If the folks at phpBB would release a version with integrated sign-in from the major social media platforms, I would resurrect the RF Cafe Forums, but until then it is probably not worth the effort. Regardless, there are still lots of great posts in the archive that ware worth looking at.

Hello,

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 ?
Thanks

Franck

If you need a design of a filter, there is a program on the website:http://tonnesoftware.com/. 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:

https://www.rfcafe.com/references/electr ... 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.
