From: jasonkee111 on 5 Nov 2009 12:54 Hi. i read a lot of article focusing on real input. In physical world, does the input in complex form? If exist, where it comes from and what is the application? Or actually it is just theory only? Thanks

Complex arithmetic is a simplified way to deal with complicated mathematics. It isn't "only theory". It deals with actual things.

One is real which we can measure and other is imaginary which we can not measure. The imaginary side always exist and it can be easily prove by simple mathematics. You can obtain imaginary side of any data using by Hilbert Transform of real side of that data. Kadir
