adding noise to y = a sin(w*t)

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
