in fourier transforms of normal baseband sigal , spectral components are replicated on both +ve and -ve sides of frequency axis.(adsbygoogle = window.adsbygoogle || []).push({});

i know that both -ve and +ve frequency components contribute to the total power of the signal

but i dont know the physical significance of the -ve frequencies used?

are these -ve frequencies just the mathematical imaginary tool ?
