What's the most desired topic in DSP????

Question

Hey Everybody,

Guys, Anybody out there knows what is the most, and I mean the most, practical major in Digital Signal Processing? Ok, Let me put it this way, DSP covers wide range of sub-majors, such as image/speech processing, video compression,..etc (not to mention all), So anybody knows exactly the most challenging, and desired sub-major of the above??? preferably some1 who does this kind of work!!

Cheers guys..

Answer 1

The most practical is probably telephony.  Every time someone in North America makes a phone call, DSP is going on.

The most challenging is probably cryptography or forensics, or radar detection.

The most desired is probably the entertainment industry (television / film).
