Hi Archana,
the symbol rate for bluetooth low energy is 1Ms/s(megabit/sec) for GFSK modulations...

Thanks..for the response..
But, can you please explain the meaning of symbol rate...How is it different from bit rate?

Hello Archana,
Bit rate is a measure of the number of data bits (that's 0's and 1's) transmitted in one second. A figure of 2400 bits per second means 2400 zeros or ones can be transmitted in one second, hence the abbreviation 'bps'.
Baud rate or symbol rate by definition means the number of times a signal in a communications channel changes state. For example, a 2400 baud rate means that the channel can change states up to 2400 times per second. When I say 'change state' I mean that it can change from 0 to 1 up to 2400 times per second.

Hello, Bit rate - simply it refers number of bits per second. but, symbol rate - refers number of symbols per second and here each symbol may occupy atleast 2 bits. for example: In QPSK modulation, we represent each symbol as 2 bits. |

Thanks..for the response.. But, can you please explain the meaning of symbol rate...How is it different from bit rate? Symbols = 2^Number of Bit(s) If Number of Bits = 1, Then there is Two possible symbol : symbol_0 and symbol_1; If Number of Bits = 2, Then there is Four possible symbol : symbol_00, symbol_01, symbol_10, symbol_11; |
