Shannon's law
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 log
2(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.
