canonical forms

zzz
Hi all,

I was recently reading the book "Write Great code by ryndall Hyde" in
this in chapter 8 the following are given.

given n input variables there are two raised to two raised to n
unique Boolean functions ex:- for 2 i/p variables there are 16
different functions.

then he mentions about canonical forms. he says about sum of min terms
and sum of product form.

now my questions are as follows

1) what exactly is the purpose of canonical forms,especially sum of
min terms, where is it applied??

2)author says that for each different Boolean function, we can choose
a single canonical representation of that function.
I am not getting this point, can any one explain

Did you not post this question in comp.programming a couple of days
ago? Even if you are not the same poster, there are excellent answers
in that thread:
