The delayed sig- nal is then added to and subtracted from the signal of the current line to produce separate U and V signals. The precise value of the required delay is very slightly less than one line duration; this is because the number of cycles per line always ends with a half cycle and the delay must correspond to a whole number of sub-carriers.  <\/p>\n<p align=\"justify\">Let us assume that the chrominance signal going into the delay line driver in Figure 14.5 is unswitched, i.e. U + V. The chrominance signal at the output of the delayed line is that of the preceding line, i.e. switched line U &#8211; V. Addition of the two signals gives  <\/p><div class=\"uqvak6a0dcb5b45745\" ><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-0778475562755157\"\n     crossorigin=\"anonymous\"><\/script>\n<!-- 300x600 television-and-video -->\n<ins class=\"adsbygoogle\"\n     style=\"display:inline-block;width:300px;height:600px\"\n     data-ad-client=\"ca-pub-0778475562755157\"\n     data-ad-slot=\"6549443290\"><\/ins>\n<script>\n     (adsbygoogle = window.adsbygoogle || []).push({});\n<\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.uqvak6a0dcb5b45745 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.uqvak6a0dcb5b45745 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.uqvak6a0dcb5b45745 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.uqvak6a0dcb5b45745 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.uqvak6a0dcb5b45745 {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n<div class=\"gwlha6a0dcb5b4569b\" ><script type=\"text\/javascript\">\n\tatOptions = {\n\t\t'key' : '0c1eb4c533eaedb7b996f49a5a4983a9',\n\t\t'format' : 'iframe',\n\t\t'height' : 300,\n\t\t'width' : 160,\n\t\t'params' : {}\n\t};\n<\/script>\n<script type=\"text\/javascript\" src=\"\/\/www.highperformanceformat.com\/0c1eb4c533eaedb7b996f49a5a4983a9\/invoke.js\"><\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.gwlha6a0dcb5b4569b {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.gwlha6a0dcb5b4569b {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.gwlha6a0dcb5b4569b {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.gwlha6a0dcb5b4569b {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.gwlha6a0dcb5b4569b {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-pGKEy7VjVWc\/VeQt0_Gb9TI\/AAAAAAAB5U4\/42oQFU9Mjvk\/s1600-h\/Television-receivers--colour-process%25255B2%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Television receivers- colour processing-type-0005\" border=\"0\" alt=\"Television receivers- colour processing-type-0005\" src=\"http:\/\/lh3.googleusercontent.com\/-Xh8Lf3uh-84\/VeQt4inaVYI\/AAAAAAAB5VA\/i4wfRFhMfRM\/Television-receivers--colour-process.jpg?imgmax=800\" width=\"500\" height=\"406\" \/><\/a>  <\/p>\n<p align=\"justify\">But the subtraction is reversed (U &#8211; V) &#8211; (U + V) = \u20132V The U and V separator thus retains the phase reversal of the V component and also removes the phase error.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>U and V separation Figure 14.5 shows how the PAL-D system separates the U and V components; the chrominance signal of the previous line is stored or delayed for one line duration (64 f.s for PAL and 63.59 f.s for NTSC).
