Doing some research before i proposed my project. I read from the DSP e-book and i learn of how to the FM stereo component work... Now i was thinking how to apply to a matlab or mathcad... Is there a way to generate out from the software? such like generate out the output graph that look like the component of FM stereo with the RDS. Is this project valuable to do? Plz comment... Thankz.

Need to hand in my proposal next week. So was thinking whether to proposed my theoretical as Matlab software solution... Any idea on Matlab? Thankz

But well im not that good in Mathcad so i choosed Matlab. |
