What is the effect of changing standard deviation of Gaussian Filter in removing noise?

Code:
clc
clear all
close all
warning off
x=cumsum(randn(1,10000));
g=fspecial('gaussian',[1 50],2);
y=conv(x,g);
plot(x,'b');
hold on;
plot(y,'r','linewidth',2);
g=fspecial('gaussian',[1 50],10);
ya=conv(x,g);
plot(ya,'g','linewidth',2);
legend('Noisy Signal','SD 2','SD 10');

How to remove the phase lag in this case?

[@ajayjoseph4498]

What do you suggest if u have to reduce the phase lag?

[@antoine1407]

I am curious
