Key Differences
Bit Rate refers to the number of bits transmitted per second in a communication channel. Baud Rate refers to the number of signal changes or symbols transmitted per second.
High bit rate means more data is transmitted in a given time, beneficial for data-heavy applications. High baud rate means the channel is changing its state more frequently, which doesn't always imply more data transmission.
Bit Rate is measured in bits per second (bps). Baud Rate is measured in bauds, which signify the number of times the signal changes state.
Bit Rate directly corresponds to the amount of data transmitted or received over a network. Baud Rate, however, is about how often the physical state of the connection changes.
In digital communications, bit rate is a key performance metric, as higher bit rates indicate more data transfer capacity. Baud rate is essential in understanding how efficiently a channel uses its bandwidth.
