A course in signal analysis and communication would have introuduced the concept of a "negative frequency" to anyone. A negative frequency component pops up everywhere whenever we deal with modulations AM(DSB,SSB,VSB,ISB).
A spectral analysis of a modulated signal has harmonics in both positive and negative frequency scale. Now I wonder what is the significance of this negative frequency component in practical sense. Does it have any implication in design of transmitters. Do negative frequency components really exist?????Is it realizable??
Please keep the mathematical part to minimum as possible....
