Single Sideband Modulation (SSB-SC) Explained | Hilbert Transform | Single Sideband Demodulation

In this video, a brief introduction of Single Sideband Modulation (SSB-SC) is given, and with the help of the Hilbert Transform, the mathematical expression of the Single Sideband Modulated signal is found. And at the later part of the video, how the SSB signal can be coherently demodulated is also explained.

Single Sideband Modulation:

Single Sideband Modulation is one type of amplitude modulation where only one sideband is transmitted.
Since upper and lower sideband carries the same information, any one of them can be suppressed and only one sideband can be transmitted.

If the message signal has bandwidth B then the bandwidth required for transmitting the SSB-SC signal is also B.
While in DSB-SC and conventional AM signal, the required bandwidth is 2B.
Therefore it is bandwidth efficient modulation scheme. Typically SSB Modulation is used for voice signals. And when the carrier signal is suppressed then the SSB signal can be demodulated coherently at the receiver end.

Advantages of SSB modulation
1) It is bandwidth efficient modulation scheme.
2) The transmitted power requirement is less than DSB-SC and conventional AM
