PLL simulation in MATLAB

Hi everybody

I have noise flie in text format of my VCO.
How to add the noise in the simulink model of PLL using this text file.

thanks

Re: PLL simulation in MATLAB

If you using simulink you can use a simulink object called "From File", in the "Sources" library. You can open any file with it but you must make sure the data in your file is formatted accordingly.

If your not using simulink you can write some MatLab code to open the file and exctract the data. It's quite easy. The syntax is very simillar to C.

There is another option in case you're using simulink and your data is not formatted. You can write the code to extract data, like I said, do any data convertion or formatting you want, and then store it in an array in Workspace. Then you use the "From Workspace" object to use your data in Simulink.

Hope it helped. Peace man.

Thanks i will search and try this one.

But can i use the extracted data from my noise text file in VCO block available in simulink , if so pls give some details .

thanks
