Hello,
I understand you are trying to normalize the signals two signals to bring them to same scale for comparison. You can try 'min-max normalization' to normalize both the signals to the range [0,1].
Hereby is an example code in MATLAB R2018a for your reference:
t=linspace(0,2*pi,100);
y=5*sin(t);
step_size=10/20;
partition=-2*pi:step:2*pi;
y_Quant=quantiz(y,p);
norm_y=(y-min(y))/(max(y)-min(y)); %%min-max normalization
norm_yQuant=(yQuant-min(yQuant))/(max(yQuant)-min(yQuant));
figure;
subplot(211);
plot(norm_y);
subplot(212);
plot(norm_yQuant)
Both the signals before and after quantization are normalized to same scale for comparison.
Hope this helps...
