GA Review[edit]

This review is transcluded from Talk:M-derived filter/GA1. The edit link for this section can be used to add comments to the review.

Hi, I think this article has potential but needs better sourcing.

The lead appears to be WP:OR. Please add a source for the claims made. A lead does not have to be sourced if the points made in the lead are made elsewhere in the article properly sourced of course. The is does not appear to be the case here.
The derivation section is unsourced.
The operating frequency section is inadequately sourced. Please point to the specif page in Bode's patent that shows this derivation. In a cursory review I couldn't find it. Note that in a good article, the reader should not have to wade through an entire reference to verify the claim.
Image impedance section is unsourced
Ditto Prototype transformations
Ditto Cascading sections

Generally, the derivations are mostly from Matthaei, I will sort out some inline cites and mark the sections below as I get them done. The Bode patent is not a cite for the operating frequencies (which are well known and in any number of sources) but rather to verify the the rather more obscure claim that the circuit is no good below m=0.2.

Lead - done
Derivation section - done
Operating frequency section - done
Image impedance section - done
Prototype transform section - done
Cascading section - done

Noting that the reviewer has stopped editing, so a new one needs to take over. Wizardman _{Operation Big Bear} 15:18, 12 April 2010 (UTC)[reply]

Review by MuZemike[edit]

Passed. Besides a few very minor prose issues, the sources do check out, it looks comprehensive enough (given that this is a very narrowly-focused topic), the lead and layout the good, and it's neutral in tone. Looks like everything that the first reviewer addressed were adequately addressed. Good job. –MuZemike 23:41, 14 April 2010 (UTC)[reply]
