What is Normalisation in signal processing?

Normalization refers to the conversion of the signal to a scale relative to a known and repeatable value.

How do you normalize a signal in Matlab?

N = normalize( A ) returns the vectorwise z-score of the data in A with center 0 and standard deviation 1. If A is a vector, then normalize operates on the entire vector A . If A is a matrix, then normalize operates on each column of A separately.

How do you normalize a frequency spectrum?

You need only divide the frequency in cycles by the number of samples. For example, a frequency of two cycles is divided by 50 samples, resulting in a normalized frequency of f = 1/25 cycles/sample.
