Difference between bit rate and baud rate and its origins?

Everyone seems to have different definitions everywhere I look. According to my lecturer: \$ R_{bit} = \frac{bits}{time} \$ \$ R_{baud} = \frac{data}{time} \$ According to manufacturers : \$ R_{...

Why is the Nyquist data rate lower than the Shannon data rate?

In the book Computer Networks, the author talks about the maximum data rate of a channel. He presents the Nyquist formula : C = 2H log\$_2\$ V (bits/sec) And gives an example for a telephone line : ...

Baud rate vs. Bit rate

When we initialize a serial communication, we usually have to set the baud rate (e.g. 115200) I notice that many people assume that 115200 means 115200 bits per second. However, each baud(signal ...

Does the fundamental frequency affect the bit rate on a wire?

This is from the book Computer Networks by Tennenbaum: The bandwidth is still the width of the band of frequencies that are passed, and the information that can be carried depends only on this ...

Why is “throughput” called “bandwidth”?

But back in school, I had learned that the "bandwidth" of a communication channel is the frequency of the highest-frequency signal minus that of the lowest-frequency signal that it can carry. Yet in ...

What is the speed of a baud rate? - RN42

After wondering/researching about this for days, I finally ask this question: What is the speed (bits per second) of a bluetooth SPP RN-42 device? Is 1 baud = 1 bit (thus 9600 baud = 9600 bits per ...
