What is vestigial side band transmission?
Vestigial sideband (VSB) is a type of amplitude modulation ( AM ) technique (sometimes called VSB-AM ) that encodes data by varying the amplitude of a single carrier frequency . Portions of one of the redundant sidebands are removed to form a vestigial sideband signal - so-called because a vestige of the sideband remains.
What is the merits and demerits of vestigial side band transmission?
v,kjhj;
Why vestigial side band technique in video transmission?
why it is used for picture or video transmission
What is advantage of single side band?
An advantage of a single side band (SSB) is that it only needs half the bandwidth of AM. AM stands for amplitude modulation.
What is SSB radio?
'SSB' stands for "single sideband modulation".
Which are the three forms of modulation?
There are actually 4 forms. The first and most common is AM, the next is SSB or Single Side band, the third is FM (Frequency Modulation) and the fourth is Digital
What is meant by single side band modulation?
Single side band suppressed carrier modulation is like amplitude modulation except that one of the sidebands is suppressed or filtered out. Each sideband carries the same though opposite, information, so suppressing the one sideband allows more power to be placed into the one remaining sideband. The downside, of course, is that the demodulation process is more complex.
Difference between dsb lc dsb SC?
The difference between double side band long carrier (DSB LC) and double side band short carrier (DSB SC) is the is how the amplitude modulation (AM) is referenced in the carrier wave.
What are the electronic communication?
its nothing but modulation and demodulation. modulation of the message is done in transmitter side and demodulation is done at receiver side and retrieving the original message.

Where is the vestigial digit on a frog?
Frogs have 4 fingers and 1 vestigial finger, and 5 toes + 1 vestigial toe. The vestigial fingers and toes are positioned on the inner side (bode-side) of the hand/foot, pointing towards the body. In live specimens these digits are not visible, only when a frog is dissected it can be seen.
What are the Applications of double side suppressed carrier modulation?
Each of the two sidebands can be modulated independently to give two simultaneous communication channels. There would be no point in radiating the carrier, as it carries no information, and would waste transmitter power.
