vsb modulation is preferred in tv because

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