From Wikipedia, the free encyclopedia.
In telecommunication, a Shannon's law is a statement defining the theoretical maximum rate at which error-free digits can be transmitted over a bandwidth-limited channel in the presence of noise, usually expressed in the form C = W log2(1 + S /N ), where C is the channel capacity in bits per second, W is the bandwidth in hertz, and S /N is the signal-to-noise ratio in db.
Note: Error-correction codes can improve the communications performance relative to uncoded transmission, but no practical error correction coding system exists that can closely approach the theoretical performance limit given by Shannon's law.

In Arizona, Shannon's law is a law that was established after the 1999 death of teenager Shannon Smith, to punish those who take gunshots to the air, risking the lives of others.
