Difference between Bit Rate and Baud Rate

Computer NetworkInternetMCA

Bit Rate

In telecommunications and computing, "bit rate" is the number of bits communicated or processed per unit of time.

  • Bit rate is measured in bits per second (symbol: bit/s) and is commonly prefixed with a SI prefix like kilo, mega, Giga, or Tera.

  • The non-standard term "bps" is sometimes used instead of the conventional sign "bit/s". Therefore, 1 Mbps stands for one million bits per second.

  • One byte per second (1 B/s) equates to 8 bits per second in most computer and digital communication contexts.

Baud Rate

In telecommunications and electronics, a "baud" is a standard symbol rate measuring unit. It is one of the components that determine the speed of transmission across a data channel.

  • In pulses per second, symbols per second, it is the unit for symbol rate or modulation rate.

  • In a digitally modulated signal or a "bd rate line code", it is the number of unique symbol changes (signaling events) made to the transmission medium per second.

  • The term "baud" refers to the gross bit rate, which is measured in bits per second.

  • If the system only has two symbols (usually 0 and 1), baud and bit per second (bit/s) are interchangeable.

Difference between Bit Rate and Baud Rate

The following table highlights the major differences between Bit rate and Baud rate −

Bit RateBaud Rate
Bit Rate is the number of bits sent per second.The number of signal units per second is known as the Baud Rate.
Bit Rate is calculated by multiplying the baud rate by the number of bits per baud.Baud Rate is calculated by multiplying the Bit Rate by the number of bits per baud.
Bit Rate is not utilized to determine the amount of bandwidth required for signal transmission.Baud Rate is used to determine the amount of bandwidth required for signal transmission.
Bit Rate is sometimes defined as the number of bits that move per second.The number of changes in signal per second is also known as the Baud Rate.
Computer efficiency was prioritized above bit rate.Baud Rate, on the other hand, is focused on data transfer.
