VSB modulation has become standard for the transmission of Television signals. 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. Therefore VSB ( Vestigial Side Band) transmisson is preferred 3. 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. Post navigation. This results in a DC offset of the baseband signal. A VSB signal can be plotted as shown in the following figure. In TV Transmission the use of FM is made for Audio transmission and AM for Video transmission. Describe the accounting process used to account for frequent flyer points prior to the adoption.. Actually Double Side band transmission is not wasting any data while traonsmission. D. None of the above. This is the job of the 8-VSB exciter. For TV transmission, Both AM and FM are used. B. Vestigial Sideband modulation (VSB) is used for the following reasons : 1. SSB requires less bandwidth. 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. errors) to the eager consumer waiting at home in front of the TV set. It reduces the bandwidth requirement to half. But the problem with DSB is its bandwidth required is more. Vestigial Sideband Modulation or VSB Modulation is the process where a part of the signal called as vestige is modulated, along with one sideband. 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. 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. 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 because TV information gives you two types of information- audio and video. 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. Figure 1 is a block diagram of a typical 8-VSB exciter. 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 Uploaded by: ChefThunderGerbil Along with the upper sideband, a part of the lower sideband is also being transmitted in this technique. Which one of the following is analog? In single-sideband modulation, a DC offset at the input to the modulator results in a fixed amplitude component at the carrier frequency. Video signal exhibits a large bandwidth and significant low-frequency content which suggests the use of VSB 2. It avoids phase distortion at low frequencies. VSB modulation is preferred in TV because A. Answer & Solution Discuss in Board Save for Later 28. The 8-VSB system, a part of the baseband signal ) to the eager consumer waiting at home front.
