In signal processing, the Nyquist rate is two times the bandwidth of a band limited signal or a band limited channel.

The Nyquist bit rate formula is use to calculate the theoretical maximum bit rate.

```
Bit rate=2*bandwidth*log2L
```

Where bandwidth is the bandwidth of the channel, āLā is the signal level used to represent data.
