Baud Rate Rechner
Berechnen Sie den relationship between baud rate und bit rate for UART, RS-232, and other serial links.
Gross Bit Rate
9,600 bps
Gross Bit Rate vs Baud Rate (symbols/s)
Formel
## 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).
Lösungsbeispiel
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%
Häufig Gestellte Fragen
What is the difference between baud and bps?
Baud is symbols per second. Bps is bits per second. They are equal only when each symbol carries one bit (e.g., basic UART).
How can bit rate exceed baud rate?
With multi-level modulation (QAM, PSK) each symbol encodes multiple bits. QAM-256 sends 8 bits per symbol.
Common UART baud rates?
9600, 19200, 38400, 57600, 115200. Higher rates require shorter cables or better line drivers.
