Bit rate defines the amount of data or information that is transmitted from a source during a specified time period. Bandwidth is the maximum rate at which bits can be transferred from a source to a destination across a given path or medium.

How do you calculate bandwidth from bit rate?
C(bps) = 2B * log2M (Nyquist)
C is the capacity in bits per second, B is the frequency bandwidth in Hertz, and M is the number of levels a single symbol can take on. This "idealized" capacity equation shows us that data rate is proportional to twice the bandwidth and logarithmically proportional to M.
What is difference between bandwidth and data rate?
Bandwidth is a measure of the transmission capacity of a network over a specific period of time. It is the rate at which a link may send or receive bits per second. Data rate is used to measure how fast data is transferred from one point to another. It refers to the actual amount of data transferred.
Can bitrate be higher than bandwidth?
Bitrate can never exceed Bandwidth, but Bandwidth can be larger than one connection's bitrate. For example, your Internet connection can have a maximal bandwidth, and you may have more than one process connecting over the Internet, each with its own bitrate.
What is the relationship between baud rate bit rate and bandwidth?
The bandwidth of a digital signal is the number of bits transmitted per second. The baud rate is the number of signalling elements transmitted per second. In simple systems each signalling element encodes one bit, so the two values are the same.
