Learning objective
Communication basics: Define: • baud rate • bit rate • bandwidth • latency • protocol. Differentiate between baud rate and bit rate. Bit rate can be higher than baud rate if more than one bit is encoded in each signal change. Understand the relationship between bit rate and bandwidth. Bit rate is directly proportionate to bandwidth. 82

Quick student answer
Which definition best describes baud rate?
Direct answer
The number of signal changes per second
Key terms
- Bit rate: The number of bits transmitted per second.
- Baud rate: The number of signal changes per second.
Common trap
Confusing baud rate with bit rate: Baud rate counts signal changes per second, while bit rate counts bits per second. If more than one bit is encoded in each signal change, bit rate is higher than baud rate.
