I've been reading about SSB amplitude modulation, and I am kind of confused about something. Book says you can filter/phase out the carrier wave which would eliminate the LSB or USB thus increasing efficiency and cuting used bandwidth in half. What I don't under stand how this work? First off, I thought it was aplitude modulation. It shows a picture of a spectrum analyzer (Frequency [horizontal] vs. Amplitude in dBm [vertical]) graph and shows that a voice is deviated away from the carrier signal evenly in both ways equal to the bandwidth of themodulated signal! I thought it was amplitude modulation how is it getting away from the carrier freaquency?? Sorry for my ignorance I am new to electronics. I understand the voice has frequences too but I thought the frequencies of the voice only affected the amplitude of the carrier wave?? And why is it a mirror image? If I had to guess I would figure it would go Half the bandwidth of the modulated signal in both ways???? Thanks for any help!
