通过将每个脉冲中的Bit/脉冲中的信息作为可以发送的不同消息M的数量的2的对数，Hartley<ref>{{cite book | title = Information Theory; and its Engineering Applications | author = D. A. Bell | edition = 3rd | year = 1962 | publisher = Pitman | location = New York}}</ref>构造了一种测量线速R的方法：
然后可以根据一下公式计算出先速率R的值：

公式中<math>f_{p}</math>为脉冲速率，也称之为符号率，单位为符号/秒(symbols/second)或波特(baud)。
Hartley then combined the above quantification with Nyquist's observation that the number of independent pulses that could be put through a channel of bandwidth {\displaystyle B} B hertz was {\displaystyle 2B} 2B pulses per second, to arrive at his quantitative measure for achievable line rate.
哈特利(Hartley)随后将上述量化结论与奈奎斯特的观察结合起来，观察到可以通过带宽信道放置的独立脉冲数 {\ displaystyle B}B赫兹原为{\ displaystyle 2B}2B 每秒脉冲数，以得出可达到的线路速率的量化指标。
Hartley's law is sometimes quoted as just a proportionality between the analog bandwidth, {\displaystyle B} B, in Hertz and what today is called the digital bandwidth, {\displaystyle R} R, in bit/s.[3] Other times it is quoted in this more quantitative form, as an achievable line rate of {\displaystyle R} R bits per second:
