Getting more involved with DSP. Before I start buying books and development kits I would like to know a bit more about FFT. Basically what I would like to know is if FFT did not exist what would we not be able to do in DSP? In other words what is the benefit of FFT? and compared to regular FT?
And lastly FT is just converting a time signal into the frequency domain, correct? So my question is, is a spectrum analyzer a time domain to frequency converter? Does a SA do FFT or just FT?
ANy help is appreciated.
