Assertion (A) : A self-biased circuit has a better stability than a fixed bias circuit. Reason (R) : It provides negative feed back by the use of an additional resistor between the base and ground. 67. Assertion (A) : Optical fibers have broader bandwidth compared to conventional copper cables. Reason (R) : Low power LASER beams are considered to be very powerful as compared to high power ordinary light beams. 68. Assertion (A) : A demultiplexer can be used as a decoder. Reason (R) : A demultiplexer is built by using AND gates only. 69. Directions : Q. Nos 61 to 70 : The following items consist of two statements, one labelled the Assertion (A) and the other labelled the Reason (R) . You are to examine these two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so, whether the Reason is a correct explanation of the Assertion. Select your answers to these items using the codes given below and mark your answer accordingly. Assertion (A) : In serial communication system, when the transmission of data goes in both ways, it is called full-duplex system. Now if two micro processors are connected in full duplex mode, the amount of data transmitted will be double to the amount of data in half-duplex mode connection. Reason (R) : When the transmission of data goes in one way, it is called halfduplex system and when the data moves in both ways, it is called full duplex system. Assertion (A) : Reason (R) : Codes : (A) Both (A) and (R) are correct and (R) is correct explanation of (A). (B) Both (A) and (R) are correct, but (R) is not correct explanation of (A). (C) (A) is true, but (R) is false. (D) (A) is false, but (R) is true. 61. Assertion (A) : TWTA is a narrow band device and has a helical structure and it is used as amplifier and oscillator. Reason (R) : In TWT, the electron beam travels through a slow-wave structure and speed 1 of electron beam is of the 10 velocity of light. 62. Assertion (A) : An Op-Amp is a direct coupled high gain amplifier. Reason (R) : It consists of one or more differential amplifiers and usually followed by a level translator and push pull stage. 63. Assertion (A) : To have a high sensitivity, a low value of gauge factor is desirable. Reason (R) : Semi-conductor strain gauges are made up of Si and Ge and show piezoresistive effect. Paper-III 10 J-88-14 70. Assertion (A) : In control systems, steady state response in the final requirement for calculating the efficiency of the system. Reason (R) : The transient response is also critical for the determination of the steady state response. 71. One of the reasons why vacuum tubes eventually fail at microwave frequencies in that their (A) transit time becomes too short (B) shunt capacitive reactance becomes too large (C) series inductive reactance becomes too small (D) noise figure increases 72. The Multicavity Klystron (A) is not low-level amplifier because of noise (B) has a high repeller voltage to ensure a rapid transit time. (C) is not suitable for pulsed operation (D) needs a long transit time through the buncher cavity to ensure current modulation 73. The primary of the helix in a travelling wave tube is to (A) prevent the electron beam from spreading in the long tube (B) reduce the axial velocity of the RF field (C) ensure broadband operation (D) reduce the noise figure 74. One of the following is unlikely to be used as a pulsed device. It is the (A) TWT (B) CFA (C) BWO (D) Multicavity Klystron 75. Indicate the false statement. Klystron amplifiers may use intermediate cavities to (A) prevent the oscillations that occur in two cavity Klystrons (B) increase the bandwidth of the device (C) improve the power gain (D) increase the efficiency of the Klystron Read the paragraph and answer the question 71 to 75 : Microwave tubes are used as microwave amplifiers and oscillators. Three general type of microwave tubes in which third type tubes are important because in these tubes there is an interaction between an electron and an RF field is continuous. The Travelling Wave Tube (TWT) is the prime example of this interaction. It is an amplifier, whose oscillator counter part is called Backward Wave Oscillator (BWO). The second sub-group consists of tubes in which a magnetic field ensures a constant electron beam RF field interaction, and this is complemented by the Cross-Field Amplifier (CFA). Multicavity Klystron is used as high and very high power amplifiers in the UHF and microwave ranges. The frequency range covered is from about 250 MHz to over 95 GHz. The reflex-Klystron is a low power microwave oscillator. It is assumed that oscillations are started by switching transients. For oscillations to be maintained the transient time in the repeller space cycle is given as 3 T = n + 4 where n is an integer, each value of n is said to correspond to different reflex klystron mode. Reflex Klystrons with integral cavities are available in the frequency range 4 to 200 GHz. J-88-14 11 Paper-III Space For Rough Work Paper-III 12 J-88-14
