#### Symbol rate

• abstract: In digital communications, symbol rate (also known as baud or modulation rate) is the number of symbol changes (waveform changes or signalling events) made to the transmission medium per second using a digitally modulated signal or a line code. The Symbol rate is measured in baud (Bd) or symbols/second.

symbol rate

SR：符率 (Symbol Rate)在数字电视中信号是以数码形式传输的。在一个数码单元时间内发送一个符号 (Symbol)。例如 0 或者 1 可以是符号。在卫星电视中电磁波以正弦振荡形式发射。这个正弦振荡的相位可以在数码单元时间内变为0，90，180 或者270度。这些相位就是符号。一秒钟内发送的符号数目就是符率。实际上这个正弦振荡 (载波) 通常被多个电视节目轮流分享使用符率是各个节目共同使用的总和再加上开销。例如一个载波的符率为20兆符/秒共有6个电视节目分享。那么一个电视节目的符率大约只有3兆符/秒。
