The Dome Hilbert Filter

[Francesco Balena]

Hi,
can anyone provide the original, seminal paper:

R. B. Dome, "Wideband Phase Shift Networks," Electronics, Dec 1946, p 112

It is the seminal paper about an analog audio wide band Hilbert filter.
The Hilbert filter shifts 90° all the frequency components in the audio band ( 20 Hz -:-20k Hz ).
Thank you fb

Can't guarantee you'll find what you are looking for here, but it is a good place to start, and you'll find lots of other stuff of interest:

tubebooks.org - Vintage info from the age of vacuum tubes

You may also want to look on the internet archive.

Yes, and archive.org; but Dome is not there.

Many-many audio/electronic magazines
Electronics Magazine, 1930-1969 (most)
Cited page 112 is page 132 of the (69Meg!) PDF for Dec 1946.

This issue also has Scott's Dynamic Noise Suppression. (3 times-- scanner slip)

I must need some sleep or have low blood sugar as I read it as
The Home Dilbert Filter 😀

Finally the R. B. Dome article

dear "kevinkr": thank you;
dear "scott wurcer" : yes I know this site, very good!
dear "mirlo" : 😀🙂😀🙂😱 sorry!
dear "PRR" : WOW! WOW! WOW ! What a wonderfull mess of information! Thank you, thank you very much! FINALLY the R. B. Dome phase shift article !!!!! Dear "PRRR" can I be your slave for... let me say 1 year.. no no ! 1 week ? fb
