First we consider some examples.
\begin{Example}For a given
set vector of bits $S$, for example
$S=\(x,y,z\)$, $S=\(x,y,z\)\in \Fb^3$, we define the "parity bit" a new bit that is $1$ if the number of bits $1$
in $S$ is odd, $0$ otherwise. To compute the parity bit we define a function
$f$, $f$ on
the bits in $S$, that
input of the function that gives as output the
. For example if $S$ has $3$ bits, that is
$S=\{x,y,z\}$, we have if the
function $f:(\Fb)^3 bits are $n=3$
\[
f:(\Fb)^3 \rightarrow
\Fb$, that is $f(x,y,z)=x+y+z$ \Fb,
\]
where
$x+y+z\in \Fb$. $f(x,y,z)=x+y+z$.
\end{Example}
Verify that the new bit $f(x,y,z)$ is the parity bit.
