Q11. If the bandwidth is increased by 2, the yfm and yam (where y is the ratio of SNR of output to SNR at input, fm is frequency modulation and am is amplitude modulation) is increased by a factor of, Q9. Broadband Aerials (trading as Broadband Communications), is a CAI Plus registered company who have been involved in the installation of aerial and satellite equipment, and more recently in television wall mounting installations and door entry, since 1993. Broadband long-distance communications were made possible by the advent of. In the context of Internet access , broadband is used to mean any high-speed Internet access that is always on and faster than dial-up access over traditional analog or ISDN PSTN services. Which of the following frequency is least likely to be present in the output? Which of the following has the highest input impedance? lines, allow us to easily access multimedia services (data, voice, and video) in one subscriber lines (DSL), cable modems, and passive optical networks, as well as explore (PCS), and satellite communications. According to Gartner Inc., households with a broadband connection will reach 25% of the world total by 2012, from only 18% in 2007. Broadband networks, such as asynchronous transfer mode (ATM), frame relay, and leased Subject: Broadband Communication Systems 3. Standing waves will be set up if, c) Both amplitude and frequency modulation, d) Neither amplitude nor frequency modulation, Q16. Also, at the end of each chapter, there are review questions with answers that allow the reader to check his or her level of understanding of the material, as well as problems-test questions for which no answers are provided. In ccir-b system, the time between start of one h syn. An earth mat for a communication tower consists of, a) One or two radials extending from base of tower at a depth of about 5 cm below ground, b) A large number of radials extending from base of tower at a depth of about 3 m, c) a large number of radials extending from base of tower at a depth of about 30 cm, a) Adding magnetism in mask and mounting frame, b) Removing residual magnetism in mask, shield etc…, c) Increasing resistance of coils to decrease time constant, d) Decreasing resistance of coils to increase time constant, Q3.
