Which among the following types can be regarded as a pristine or conventional form of Amplitude Modulation?

Which among the following types can be regarded as a pristine or conventional form of Amplitude Modulation?

a. DSB-SC
b. DSB-LC
c. SSB
d. VSB

Correct Answer : b. DSB-LC

Explanation :

DSB- LC can be easily obtained by addition of large carrier component to DSB-SC,which is a more simpler form of amplitude modulation. On the contrary, VSB involves the composite signal for transmission purpose, SSB consists of frequency & phase determination methods. Apart from these, DSB-SC is basically a multiplier & simplest among the linear methods mentioned above.
