Title

It's a bit unfair that this design is credited uniquely to Clapp. Surely it would be better to have this page itself named "Gouriet/Clapp Oscillator" and have a pair of redirects to it from 'Clapp_oscillator', and from 'Gouriet_oscillator'?

I have just put up a page on G.G. Gouriet and it has the slightly odd-looking case of a reference to his oscillator design that actually takes the reader to this page, entitled "Clapp Oscillator"! The BBC have documented evidence that Gouriet's design was in use from 1938, ten years before Clapp's publication. No discredit to Clapp intended - he discovered the same design independently.

So what does the literature say? We don't pick the names for things here (or we shouldn't), we calls 'em as we sees 'em. --Wtshymanski (talk) 14:08, 8 December 2010 (UTC)[reply]

It's a fair point. Only one reference on internet seems to be inclined to call it the Gouriet-Clapp circuit. I've reworked the Gouriet page to make it more obvious that the circuit is usually known as the Clapp. Steve Hosgood (talk) 23:13, 8 December 2010 (UTC)[reply]

At least in the Book by Andrei Grebennikov, RF and Microwave Oscillator Design, Wiley 2007, P. 40, the circuit is called Gouriet-Clapp oscillator. But this seems to become visible only in newer books. So the common name is still Clapp-Osciallator. I think that both articles are now clear enough on this subject, once I have added this link at least in this article. Rainglasz (talk) 15:04, 9 December 2010 (UTC)[reply]

Crystal Oscillators vs. High Stability LC Oscillators

The plot thickens! It is probably outside Wikipedia's remit to pass comment (in the actual articles) about this, but a re-read of Ref [1] in my article on Gouriet reveals no indication that Gouriet nor the BBC had any interest in LC oscillators (as did Clapp in his 1948 paper). Gouriet's work was on the crystal-controlled oscillator. Maybe Clapp should indeed be hailed as sole documented developer of the LC variant of the oscillator that bears his name, and only in the case of the crystal-controlled variant should Gouriet's claim to fame come in.— Preceding unsigned comment added by Steve Hosgood (talk • contribs) 12 dec 2010 00:37‎ (UTC)

There seems to be no contemporary publication where Gouriets name is directly associated with a specific circuit. We have so far only two sources, the Vacar article and the BBC report, directly on this subject. So we cannot terminate the historical debate here, and the current state is fair for both.

Oscillation frequency equation

The equation seems to be wrong.147.32.229.157 (talk) 01:14, 9 January 2013 (UTC)[reply]

Can you prove it with a source of a demonstration? ICE77 (talk) 01:55, 1 August 2015 (UTC)[reply]

Question and comment

1. The caption in the image says "direct-current biasing network not shown". Would it be possible to update the image with a circuit that includes the biasing network? Also, is the FET a JFET or a MOSFET?

2. According to the article on Geoffrey George Gouriet, the Clapp oscillator is called Gouriet-Clapp oscillator to attribute the invention to both inventors. It would be nice to add the information to this article and maybe go as far as renaming this entry.
