You have not responded to my question...
The problem for me it to know what I can suppose
you knowing about the stereo multiplexing and
handling of the required operations in sampled-
data domain.
If this is a study project we definitively will
not provide you with a cook-book answer. Also, as
a consultant, I usually get paid for such work.

Hi Tauno,
I am still waiting for your help in Matlab.
I know how to plot for the pilot frequency.
But i doesnt know how to plot the L+R and L-R region on Matlab.
Please help me on how to plot those region.
Thank You

Yes, it is. It is important to direct our responses so
that we do not spoil your opportunity of learning.
It is possible to use a mathematics program to simulate
the processing in a DSP, also in your case. First, you
need to make the important design decisions how to
achieve your goal. This is the same process for a math
program and for a DSP.

If the best i will proposed my theoretical software as MathCad... But
well im not that good in Mathcad so i choosed Matlab.

Hi Tauno,
Doing some research before i proposed my project.
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

Hi Richard,
This is something i was think about.
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.

Hadn't thought of that. Perhaps that is an example of a question with
70% of the context assumed?

My guess is that he's attempting to simulate the
multiplex used on top of a FM radio transmission,
including the sub-carrier encoding, i.e. what you
get from the FM demodulator.
