Why we use normalization in Signal processing?

[engineer_eda]

Hellow,

Could anyone plz explain me what the purpose of normalizing the signal?

If we have two signal on hand, how it is used when comparing these two signals?

Thanks in advance!

Not sure what you mean by "Normalizing the signal". Stabilizing the signals could be used so that you could compare the phase relationship, or a simple voltage comparison to check gain, or even distortion.

I use a digital sound processing program (Audacity). It has a Normalizing function. It does two things: (a) removes DC component, and (b) scales the amplitude up or down so that the strongest waveform is at a set reference level.
