Transmitter Recall that AM is power and bandwidth inefficient, DSB-SC attempts to be more power efficient. Note: Similar to AM, bandwidth of the message for DSB-SC (W) is expected to be much smaller than f_c, that is: BW = W << f_c This is so that, in the frequency domain, when the cosine doubles the message, they don’t overlap The Envelope doesn’t follow the message Notice: We get phase reversals because the original message not everywhere positive, so the envelope (dashed line), doesn’t follow the message.

This receiver corrects for a changing phase shift in Double Sidebar Suppressed Modulation Recall that in the non-ideal case: We can also say: *Product modulator is just the multiplication ...

SSB Modulation attempts to be power efficient and bandwidth efficient, but it’s limited in use cases. It was originally designed for voice signals (telephones), this is because they have a unique structure with a small energy gap around 0 frequency.
