Cyril Bateman's site
From a major contributor of defunct british magazine Electronics World, unsuspected facts about capacitors, cables and other components :
It shows that harmonic distorsion analysis remains a very powerful tool to investigate their behaviour.
Many thanks to Cyril to have let his works available to the audio community.
Re: Cyril Bateman's site
why do you say 'defunct' in the above? Is EW gone?
Great that Mr. Batemen put the papers up on the web.
I dont know if EW is dead, but the editorial/managerial staff was making a Homeric effort to kill it.
As far I know, EW completely disappeared two years ago. For years, EW had some audio articles, and most of them were very innovative. I think the first I bought was in 1978 and it contained two articles whose authors were no less than Peter Baxandal ( a part of his now famous series about amplifier design) and Siegfried Linkwitz (his first audio system with active LR 24 dB crossovers and transforms).
The beginning of the end :
A very sad story.
Some interesting files show 404 error on that site, how bad. That's interesting stuff :)
I to use to subscribe to EW, it was a mine of useful information over the years. As you all say went downhill rapidly, so much so that I did'nt renew subscription about 3 years ago. I used to renew on a 5 yr basis but thought at the time the way this is going it won't be around much longer. Has the magazine totally finished now I wonder. I miss reading the articles by Cyril Bateman /Self/Duncan and all.
---Some interesting files show 404 error on that site, how bad.---
Seems to be due to limitations of bandwidth and limited downloads.
---That's interesting stuff---
O yes !
The generous mr. Bateman also put up his articles , published and some till now unpublished for all to download and read- a great many insights based on knowledge and 1000´s of measurements on capacitors, cables etc
disspelling many a myth and providing practical advice for diy´ers and pro´s alike.
If you read his stuff thoroughly, you´ll know more than many audio Guru´s !
It´s a shame if we all keep fumbling in the dark while the voodoo snakeoil capacitors and sinister cable salesmen ply their trade
At a very reasonable cost , He even sells the pcb´s and article CD for repeating his hardware designs in 1ppm thd oscillators and filters, for use in many high definition measurements
using a PC soundcard and Fft software (like the www.audiotester.de)
For measuring instantaneous thd changes while capacitors charge he made a 2&3rd harmonic realtime analyser,
and a Tdfd IMD analyser both I have not seen elsewhere-
I am genuinely impressed!
can you send me the link where mr bateman sells his pcbs / cd???
I am not sure that mr. Bateman still sells his pcb´s ready made.
his CD´s and other files are here : http://uk.geocities.com/cyrilb2@btin...wnloads_5.html,
generously , some files are downloadable directly. Some PCB´s are published in there and are not difficult to DIY or order from a local PCB source.
I will try to contact Cyril rgd pcs.
