vsb modulation is preferred in tv because

Post navigation. In TV Transmission the use of FM is made for Audio transmission and AM for Video transmission. VSB modulation is preferred in TV because A. it reduces the bandwidth requirement to half B. it avoids phase distortion at low frequencies C. it results in better reception D. none of the above View Answer Workspace Report Discuss in Forum 5. Continue to order Get a quote. In single-sideband modulation, a DC offset at the input to the modulator results in a fixed amplitude component at the carrier frequency. Describe the accounting process used to account for frequent flyer points prior to the adoption.. 3. Actually Double Side band transmission is not wasting any data while traonsmission. Which one of the following is analog? But there is no practical device exactly cut the sidebands and low frequency part contains important information. D. None of the above. But the problem with DSB is its bandwidth required is more. Vestigial Sideband modulation (VSB) is used for the following reasons : 1. Video signal exhibits a large bandwidth and significant low-frequency content which suggests the use of VSB 2. Answer & Solution Discuss in Board Save for Later 28. Vestigial Sideband Modulation or VSB Modulation is the process where a part of the signal called as vestige is modulated, along with one sideband. This results in a DC offset of the baseband signal. VSB modulation is preferred in TV because (a) it reduces the bandwidth requirement to half (b) it avoids phase distortion at low frequencies (c) it results in better reception (d) none of the above 34. For TV transmission, Both AM and FM are used. In the 8-VSB system, a pilot signal is inserted by adding an offset of 1.25 constellation units to the eight defined symbol levels. C. It results in better reception. A VSB signal can be plotted as shown in the following figure. The distance of a direct broadcasting satellite from earth's surface is about (a) 1000 km (b) 10000 km (c) 36000 km (d) 55000 km 35. VSB modulation is preferred in TV because A.it reduces the bandwidth requirement to half B.it avoids phase distortion at low frequencies C.it results in better reception D.none of the above. This is the job of the 8-VSB exciter. SSB requires less bandwidth. It avoids phase distortion at low frequencies. 8VSB is the modulation method used for broadcast in the ATSC digital television standard.ATSC and 8VSB modulation is used primarily in North America; in contrast, the DVB-T standard uses COFDM.. A modulation method specifies how the radio signal fluctuates to convey information. To deliver video signal to your TV screen, AM modulation is used. this is because TV information gives you two types of information- audio and video. Figure 1 is a block diagram of a typical 8-VSB exciter. Therefore VSB ( Vestigial Side Band) transmisson is preferred VSB modulation has become standard for the transmission of Television signals. VSB modulation is preferred in TV because A. Along with the upper sideband, a part of the lower sideband is also being transmitted in this technique. Because the video signals need a large transmission bandwidth using DSB-FC or DSF-SC techniques; This is a special type of AM system which is used mainly for the TV transmission all over the world. errors) to the eager consumer waiting at home in front of the TV set.
