Bit-rate said in a computer network of potter (baud) and often said that the baud rate (baud rate) have what relation? Nye's criterion B=2 W (ideal low communication) and B=W (ideally with communication way) how do, don't understand,,,

Great god replies,

Rate is also called the data rate, refers to the transmission rate of the data, said the amount of data transferred in the unit of time, can use the element information transmission rate and transmission rate, said

Here note: transmission rate and transmission rate, transmission rate is index according to the transmission from the host end to link, the speed of the transmission rate index, according to the rate of spread across the link is generally affected by the medium, generally close to the electromagnetic wave rate

Element transmission rate: * * * * bit-rate alias, Baud rate and modulation rate and symbol rate, etc., it said per unit time of the digital communication system transmission code element number (or signal pulse number or change the number of times), the unit is the porter (Baud), 1 potter said per second transmission of digital communication systems an element, the element can be multi-band, also can be binary, but the symbol rate has nothing to do with the hexadecimal number,

Wonderful metaphor: think into electric signal element, element transfer rate is approximately equal to the per unit time is electricity a few times,
The information transmission rate: alias information rate, bit rate, etc., said unit time transmission of digital communication systems of binary code number (i.e., bits), yuan unit is bits/SEC,

So, baud rate and bit rate is different,

Relationship: if one element n bits of information, to carry the M potter element transmission rate of the information transfer rate of M * n bit/s,
