Which are the applications of vestigial sideband?
Vestigial Sideband Transmission is used for the transmission of Television signals.Because the video signals need a large transmission bandwidth if transmitted using DSB-FC or DSB-SC techniques.
What is analog modulation?
Analog modulationIn analog modulation, the modulation is applied continuously in response to the analog information signal.Common analog modulation techniques are:Amplitude modulation (AM) (here the amplitude of the modulated signal is varied) Double-sideband modulation (DSB) Double-sideband modulation with unsuppressed carrier (DSB-WC) (used on the AM radio broadcasting band)Double-sideband suppressed-carrier transmission (DSB-SC)Double-sideband reduced carrier transmission (DSB-RC)Single-sideband modulation (SSB, or SSB-AM), SSB with carrier (SSB-WC)SSB suppressed carrier modulation (SSB-SC)Vestigial sideband modulation (VSB, or VSB-AM)Quadrature amplitude modulation (QAM)Angle modulation Frequency modulation (FM) (here the frequency of the modulated signal is varied)Phase modulation (PM) (here the phase shift of the modulated signal is varied)
What are the disadvantages of DSB-fC modulation?
in DSB-SC since carrier is suppressed,hence power consumption is reduced and nominal.The power in the modulated signal is contained in all four sidebands.The bandwidth of the DSB-SC signal is double that of the message signal, that is, BWDSB-SC =2B (Hz).How many sidebands? There's only two; upper and lower.
Difference between dsb fc dsb sc?
DSB-FC means 'dual sideband full carrier' where DSB-SC means 'dual sideband suppressed carrier'.With DSB-SC the carrier wave is suppressed so that almost all the power transmitted is in the sidebands. See the wikipedia page for more info
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.
Disadvantages of DSB-SC modulation?
-Carrier not available in receiver -Envelope detection not possible
What is the relationship between frequency modulation and the frequency carrier to the modulation index in the AM modulation?
fc>2fm
What are the applications of DSB-SC modulation?
Applications:- Analogue TV systems: to transmit color information.- For transmitting stereo information in FM sound broadcast at VHF- One important application of DSB is the transmission of color information in a TV signal.- CB radio- TV broadcasting- Air traffic control radios- Garage door opens keyless remotes- DSB-SC is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave.- DSB-SC used in stereo transmission of FM radio.- Two way radio communications.

The relationship of the bandwidth required for double-sideband emitted carrier AM to the bandwidth of the modulating signal of?
In Amplitude Modulation (AM), specifically in the case of Double Sideband Suppressed Carrier (DSB-SC) or Full Carrier (DSB-FC) AM, the required bandwidth is twice the bandwidth of the modulating signal. If the modulating signal has a bandwidth of B Hz, the bandwidth required for AM would be 2B Hz. This is because both the upper and lower sidebands of the carrier wave are utilized in the modulation process, each consuming bandwidth equivalent to the original signal.
What are the applications of vsb modulation?
Television Broadcasting
What are Advantages of DSB-SC modulation?
in DSB-SC since carrier is suppressed,hence power consumption is reduced and nominal.The power in the modulated signal is contained in all four sidebands.The bandwidth of the DSB-SC signal is double that of the message signal, that is, BWDSB-SC =2B (Hz).How many sidebands? There's only two; upper and lower.
