What does NORMALIZATION do?I am using a mathematical tool in which tables are formed and normalization of these tables are done using formula u know:
g(x)=g(x)/Max[g(x)];
i.e all values of the table are divided by the Maximum number from the table.
thus table got maximum value =1.
my question is that "what is its effect and does it provide better performance if used in algorithm."
thanks.

What is this mysterious algorithm?

Because the effects really depend on the application. If you need to compare g(x) with another function h(x), a normalization may be necessary (in the case of two sound signals). But you loose precision by doing this, so in some application, it's really not desired.
