vsb modulation is preferred in tv because

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