You can use both the methods. Adding noise in the Simulate Signal Express VI is an easy and simple solution. If you want to use the Control & Simulation loop, you can perform a numeric addition of Sine Signal and Uniform White Noise and then give the output to a Waveform Chart.

sir thanq very much .....
sir i want add some percentage of random noise to sin wave like this.......
let y=asin(w*t)
then noise signal = y+ some percentage of random noise * y sir
how can i add without putting tick mark add noise
in matlab we will do like this
clc;
clear;
A=100;
w=5;
t=1:1:20;
y=A*sin(w*t)
noise=rand(1,20);
noise=noise-0.5;
xy=noise*1/100
y1=y+xy.*y;
plot(t,y1)
this is for 1% noise
like this can i generate random no n do manipulations in labview as per above code
