What is a Normalised signal?

Normalizing the amplitude of a signal is to change the amplitude to meet a particular criterion. One type of normalization is to change the amplitude such that the signal's peak magnitude equals a specified level.

How do I normalize a filter in Matlab?

g = normalize(hd) normalizes the numerator coefficients for the filter hq to between -1 and 1 and returns the gain g due to the normalization operation. Calling normalize again does not change the coefficients. g always returns the gain returned by the first call to normalize the filter.
