What's The Use Of Fourier Transform ?
Hello Everybody ,
I started working in Fourier's analysis and transformation but the first thing i would like to know is in simple words the idea of what's the use of it.
Basically i've heard that it transforms a signal from time to frequency domain and vice versa but why does that happen / what's the benefit?
Also , i noticed that it's useful in AM modulation/demodulation , so is Fourier transform part of everyday life? Is it one of the 'hidden' techniques inside of our modems/routers or whatever and besides does it happen in every connection or in every data transmission or am i mistaken?
Thanks In Advance !!!
