It indicates how many <strong>Symbols per second<\/strong> are sent via an interface or a transmission medium. The unit of the baud rate is <strong>Baud (Bd)<\/strong>, where <strong>1 Baud of one transmitted symbol per second (1 Bd = 1\/s)<\/strong> corresponds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A symbol represents a specific signal state that is used during data transmission to encode information. Depending on the transmission method, a symbol can be <strong>contain one or more bits<\/strong>. Therefore, the baud rate is not always identical to the bit rate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The baud rate then corresponds exactly to the bit rate, <strong>if there are only two possible signal states per symbol<\/strong> (e.g. logical 0 and logical 1). In this case, each symbol has exactly <strong>One bit of information<\/strong>. However, if more than two different signal states are used, a symbol <strong>represent several bits simultaneously<\/strong>. This achieves a higher bit rate at the same baud rate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, in modulation methods with four possible symbol states per symbol <strong>two bits<\/strong> are transmitted. In this case, the bit rate is twice as high as the baud rate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the <strong>industrial communication and measurement technology<\/strong> the baud rate is a central parameter in the configuration of serial interfaces. It determines the speed at which data is transferred between devices such as <strong>Measurement data acquisition systems, sensors, control systems and software<\/strong> are transmitted. With Delphin Technology systems, the baud rate is also set according to the connected devices when setting up communication interfaces - for example with serial protocols - in order to ensure reliable and error-free data transmission.<\/p>","protected":false},"featured_media":0,"template":"","class_list":["post-6753","glossar","type-glossar","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.delphin.de\/en\/wp-json\/wp\/v2\/glossar\/6753","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=6753"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
