Another feature of this design is the detection of bits at the peaks, which gives higher accuracy. The AGC compensates the amplitude variations. This design uses the differentiator method to detect the bits at the peaks, as compared to normal zero crossing detectors.</p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;"><strong><em>Last Updated:</em></strong> 09/17/2009</p><p style="margin:0;padding:0px;">&nbsp;</p><ul><li><a class="jive-link-external-small" href="http://www.cypress.com/?docID=18304" rel="nofollow ugc noopener" target="_blank"><span class="jive-icon-sml jive-icon-doctype-acrobat"></span>AN54374.pdf</a> (736 KB)</li><li><a class="jive-link-external-small" href="http://www.cypress.com/?docID=18478" rel="nofollow ugc noopener" target="_blank"><span class="jive-icon-doctype-compressed jive-icon-sml"></span>AN54374.zip</a> (831 KB)</li></ul><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: psoc3, at:applicationnote, sp:cypress</div>
