[sdiy] Moog/Bode type frequency shifter design in EDN europe magazine

[Peter Blackett]

Hi,
I just thought you might be interested to know that in the latest issue
of EDN Europe , Jan 2004 ,
there is an article in the design idea's section for a VCO that produces
positive and negative output frequencies.the article mentions that this
is traditionally done in analog music effect units such as they
Bode/Moog frequency shifters.
Article is written by Henry Walmsley from Farnborough .
edn's web address is www.edn-europe.com
but I don't know if they have the article on line .
regards Peter
