It indicates how many <strong>Signal states or symbols per second<\/strong> be transmitted via a communication link. Formally applies: <strong>1 baud corresponds to one transmitted symbol per second (1 Bd = 1\/s)<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A symbol is a defined signal state that is used in the transmission system to transport information. Depending on the transmission method, a symbol can be <strong>contain one or more bits of information<\/strong>. Therefore, the baud rate is not necessarily identical to the bit rate. For example, if a symbol encodes several bits, the bit rate can be higher than the baud rate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In many simple serial communication processes - such as classic <strong>UART or RS-232 connections<\/strong> - corresponds to <strong>a symbol usually corresponds to a bit<\/strong>. In such cases, baud rate and bit rate are practically the same and are often used synonymously in common parlance (e.g. 9600 baud).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the <strong>Measurement and automation technology<\/strong> the baud rate plays an important role in the configuration of serial interfaces. It determines the speed at which data is transmitted between <strong>Measuring devices, control systems and software<\/strong> can be transmitted. Systems and software from Delphin Technology support different baud rates to enable reliable communication with different devices and fieldbus interfaces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The correct setting of the baud rate is a <strong>Basic prerequisite for error-free data transmission<\/strong>, as all communication partners involved must work with the same symbol rate.<\/p>","protected":false},"featured_media":0,"template":"","class_list":["post-6752","glossar","type-glossar","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar\/6752","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar"}],"about":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/types\/glossar"}],"wp:attachment":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/media?parent=6752"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
