in digital signal processing ....it is the fraction of the sampling frequency (Fn=f/Fs)

best regards

Okay ,if there's a spectrum whose frequency axis is "the normalized frequency" ,do I get the actual frequency by applying f=Fn*Fs?

generally, for use convenience, we select a reference frequency,

other frequency are divided by the reference frequency,

The result is normalized frequency.

for example, digital frequency are analog frequency's normalized

frequency to sample frequency.

Normalization as such an operation to make the function being measured dimensionless.
Say if u want to compare the spectrums of 2 (or) more signals and let each differ in their sampling frequency , by normalising they are made to be on the same X-scale and now u could make some meaningful comparison because u have eliminated the parameter which differs among the signals.
