Baud Rate vs Bit Rate
Formulas
Bit Rate = Baud Rate x Bits per Symbol
Throughput = Bit Rate x Data Bits / (Data + Overhead Bits)
UART at 9600 baud with 8N1 framing: 9600 bps gross, 7680 bps effective (80% efficient due to start/stop bits).
Example Calculation
UART at 9600 baud, 1 bit/symbol, 8 data bits, 2 overhead bits (start + stop).
- 01Gross bit rate = 9600 x 1 = 9600 bps
- 02Effective = 9600 x 8 / 10 = 7680 bps
- 03Efficiency = 8 / 10 = 80%
