What is the difference between double sideband and single sideband?

DSB removes the carrier but transmits both sidebands. SSB removes the carrier and also one of the sidebands. SSB is better but more expensive to produce. However it is easier to receive.

What is single sideband demodulation?

SSB demodulation basics

As described in previous pages, single sideband is a form of amplitude modulation where the carrier and one sideband have been suppressed or reduced in level. Single sideband modulation. In order to demodulate single sideband, SSB, it is necessary to reintroduce the carrier.

What are the demodulation methods for DSB-SC signal?

Demodulation. For DSBSC, Coherent Demodulation is done by multiplying the DSB-SC signal with the carrier signal (with the same phase as in the modulation process) just like the modulation process. This resultant signal is then passed through a low pass filter to produce a scaled version of the original message signal.

What is DSB-SC modulation and demodulation?

The modulated signal is passed through an envelope detector, which consists of a Halfwave Rectifier and an RC Filter that would detect the envelop of the modulated signal and retrieve the message signal from the DSB-FC modulated signal.
