The article details <a href="http://www.national.com/an/AN/AN-263.pdf">nine sine wave generation techniques</a>. Some techniques can be accomplished several ways so there are more than nine circuits available. The note also tabulates each technique with its frequency range, typical distortion, and amplitude stability. Both fixed frequency and adjustable frequency oscillators are covered. The simple crystal oscillator also has one of lowest distortion rates. </p> <p><img src="http://superpositioned.com/files/crystalgen.png" alt="Crystal oscillator schematic"/></p> Thu, 02 Feb 2006 07:30:00 -0800 urn:uuid:b97f3947-4a5b-4fc8-87ae-dcefd07005ca Matthew http://superpositioned.com/articles/2006/02/02/sine-wave-generation-techniques External Links schematics
