In TV Transmission the use of FM is made for Audio transmission and AM for Video transmission. Therefore VSB ( Vestigial Side Band) transmisson is preferred SSB requires less bandwidth. 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. VSB modulation has become standard for the transmission of Television signals. Which one of the following is analog? this is because TV information gives you two types of information- audio and video. It avoids phase distortion at low frequencies. Vestigial Sideband modulation (VSB) is used for the following reasons : 1. For TV transmission, Both AM and FM are used. In single-sideband modulation, a DC offset at the input to the modulator results in a fixed amplitude component at the carrier frequency. To deliver video signal to your TV screen, AM modulation is used. C. It results in better reception. Actually Double Side band transmission is not wasting any data while traonsmission. VSB modulation is preferred in TV because A. Video signal exhibits a large bandwidth and significant low-frequency content which suggests the use of VSB 2. 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. Answer & Solution Discuss in Board Save for Later 28. Post navigation. But there is no practical device exactly cut the sidebands and low frequency part contains important information. Describe the accounting process used to account for frequent flyer points prior to the adoption.. This is the job of the 8-VSB exciter. But the problem with DSB is its bandwidth required is more. 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. 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. 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. 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 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. It reduces the bandwidth requirement to half. A VSB signal can be plotted as shown in the following figure. Figure 1 is a block diagram of a typical 8-VSB exciter. B. D. None of the above. errors) to the eager consumer waiting at home in front of the TV set. 3. 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.
