To determine the baud rate, divide the bit information rate (BIR) by the number of bits per baud (BPB).
The Baud Rate Calculator is a vital tool for evaluating data transfer rates in telecommunication and serial communication systems like UART, RS-232, and CAN bus. Baud rate represents the number of signal changes (symbols) transmitted per second, while bit rate is the amount of data (bits) transmitted per second.
Formula
BR = BIR / BPB
Variable | Description |
---|---|
BR | Baud Rate (symbols per second) |
BIR | Bit Information Rate (bits per second) |
BPB | Bits per Baud (bits per symbol) |
Solved Calculations
Example 1: Calculating Baud Rate for a 9600 bps System with 1 Bit per Baud
Step | Value |
---|---|
Bit Information Rate (BIR) | 9600 bps |
Bits per Baud (BPB) | 1 |
Baud Rate (BR) | 9600 / 1 = 9600 symbols per second |
Example 2: Calculating Baud Rate for 115200 bps with 8 Bits per Baud
Step | Value |
---|---|
Bit Information Rate (BIR) | 115200 bps |
Bits per Baud (BPB) | 8 |
Baud Rate (BR) | 115200 / 8 = 14400 symbols per second |
