Double Sideband-Suppressed Carrier Modulation

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.
