Although I wrote this Note in 1970, it contains useful information on measuring precision rectifier performance. You can read the text online but you can't view any of the nine figures due to file size. To get a copy of the whole Note, click on AN103.ZIP to download it (about 793 kB). The Note is in ASCII text, the figures are .bmp and .gif files.
To get a copy of this Note, click on AN107.ZIP to download it (about 418 kB). This is a "zipped" .pdf file.
This is a very useful one-page article reprinted from the January 2007 issue of Live Sound International. This article covers the definition of the decibel (db) and most, if not all, of its variations: dBV, dBm, dBr, dBFS, etc. Just click on the above link to download the Adobe Acrobat (pdf) file. Size is about 194 kB.
This is an interesting four-page article plublished in the April 2011 issue of The Absolute Sound magazine. I think it describes the most important contribution to music restoration that has happened in many years. And I am amazed by the computer technology employed! Zenph is not a record label but they work with record companies to creat "re-performances" -- there are currently three releases from Sony. (The article size is about 1 MB.)
A one-page article published in the August 2013 issue of Sound & Vibration magazine. It briefly describes Prof. Lokki's team's work on capturing a sound hall's acoustics using a symphony orchestra simulator. This appears to be a very important contribution to the field of acoustics. (Text only but with two YouTube video addresses for more information.)
This two-page article was published in the November 2013 issue of Guitar Player nagazine. It's a brief description of Tom Doyle's work with Les Paul starting around 1965 and continuing into the 1990s. Some very interesting insights. (Color photos and text.)
