Hello,

I need to learn and have some basics at hand. I am trying to write
code for classifying raw signal data into Marks and spaces and the
like. I am also trying to extract encoding info from raw data bits and
many more things. I am stumped...at this point.

What i am lacking here is basic signal knowledge. Can you please
suggest some basic book for understangin signals, modulation, marks
and spaces, formulae or methods to determine if a stream of raw bits
indicate the presence of a carrier signal etc?

Thank you.
Ishi

Sorry this is a cb newsgroup the knowledge here is limited to making
radios go out of band or rf amplifiers.

You would do well to research code for "teletype" and cw morse decoding.
That would pretty much get you going in the right direction.

You might also research "autobaud" routines, rs232 related and similar.
There's a lot out on the web...

References for small board micro processors are a great help... you might
research the 8051, 8052 and pic controller chips.

Namaste...
