码元传输速率（Symbol transmission rate）简称传码率，又称符号速率等。它表示单位时间内传输码元的数目，单位是波特 （ Baud ），记为B。这是为了纪念电报码的发明者法国人波特（Baudot），故码元传输速率也称为[[波特率]]。 <ref>[https://baike.baidu.com/reference/6305673/aca8gpoUSBgXqm2Yo9usyp1IRKhQWMbha14VcFj5rgi_hwC_apKc6hFzstAMX_rqNeQ9oewfsF3Q4wLObjtx_zX16ntjdh-T  ] </ref> 

在[[数字通信]]中，一个数字脉冲称为一个码元。如字母A的ASCII码是01000001，可用7个脉冲来表示，亦可认为由7个码元组成。码元携带的[[信息量]]由码元的[[离散值]]个数决定。
