Types of Communication:

1) Baseband Communication
2) Carrier Communication

In Baseband Communication, the message signal is transmitted without any modification. The term baseband signal is used for the original message signal generated from the source.
Telephony is an example of baseband communication.

Carrier Communication:

The communication which uses the modulation to shift the frequency spectra of the message signal is known as the carrier communication.
So, for the frequency shifting, the high-frequency carrier signal is used. The carrier signal does not carry information but helps in carrying the message signal. It acts as an envelope. In carrier modulation, any three of the basic properties of the carrier like the amplitude, frequency, or the phase is changed according to the message or the baseband signal.

Amplitude Modulation:
In amplitude modulation, the amplitude of the carrier signal is changed according to the message signal.
Depending on the frequency spectra of the modulated signal, the Amplitude Modulation can be classified into four categories.

1) Double Side Band Suppressed Carrier (DSB-SC)
2) Double Side Band with Carrier (AM )
3) Single Side Band Modulation (SSB)
4) Vestigial Side Band Modulation (VSB)

In this video, the DSB-SC is explained and its modulation and demodulation process is explained.

In DSB-SC modulation, the bandwidth of the modulated signal is two times the modulating signal.
And since no discrete carrier signal is sent after the modulation, this type of
modulation is known as Double Side Band Suppressed Carrier.

This video will be helpful to all the students of science and engineering in understanding the Double Side Band Suppressed Carrier Modulation.
