Greetings: There is so much good stuff on RF Cafe that there is no way to list or link to
all of it here. Please use the Search box or the Site Map
to find what you want - there is a good chance I have it here. Thanks!
Gaussian Lowpass Filter Prototype Element Values (to 6 dB & to 12 dB)
The table below lists prototype element values for the normalized lowpass function, which assumes a cutoff frequency of 1 rad/sec and source and load impedances of 1 Ω. Either an input capacitor (top reference line in table) or an input inductor (bottom line in table) can be used.
Convert values to other cutoff frequencies, impedances, and to highpass, bandpass or bandstop using the denormalizing equations here.
