Shannon's law

Shannon's law (Arizona), a law against the firing of gunshots into the air, established after 14-year-old Shannon Smith was killed by a stray bullet in 1999.

What is Shannon formula?

Shannon's formula C = 12log(1+P/N) is the emblematic expression for the information capacity of a communication channel.

What does Shannon theorem state?

The Shannon capacity theorem defines the maximum amount of information, or data capacity, which can be sent over any channel or medium (wireless, coax, twister pair, fiber etc.). What this says is that higher the signal-to-noise (SNR) ratio and more the channel bandwidth, the higher the possible data rate.

What does the Shannon-Hartley theorem describe?

The Shannon-Hartley theorem describes the theoretical best that can be done based on the amount of bandwidth efficiency: the more bandwidth used, the better the Eb/No that may be achieved for error-free demodulation. Or, equivalently stated: the more bandwidth efficient, there is a sacrifice in Eb/No.

How do you calculate Shannon capacity?

C = B * log2(1+ S/N)

where C is the achievable channel capacity, B is the bandwidth of the line, S is the average signal power and N is the average noise power.
