BSNL TTA Junior Engineer Exam Pattern The test will be in an objective Manner having Multiple Choice Questions. The Exam will be conducted for a duration of 3 hours. The BNL TTA Test will be conducted for a total of 200 Marks with 200 Objective type questions. S. No Exam Paper Subject Questions Marks Duration 1 Written Test I General Ability Test 20 20 3 Hours II Basic Engineering 90 90 III Specialization 90 90 Total 200 200 BSNL TTA Syllabus Topics are given below. General Ability Test Basic Engineering Specialization Here Sample Questions for BSNL TTA JE Exam : 1) The Most Common Modulation System Used for telegraphy is FSK PSK PCM Single tone Modulation Two Tone Modulation 2) VSB is an Abbreviation if vestigial Sideband, is derived by Filtering DSB AM Either (a) or (b) PM 3) The Hartely Law State that The Maximum Rate of Information transmission depends on the Depth of Modulation The Maximum Rate of Information Depends on the channel Bandwith Only Binary Codes may be used Redundancy is Essential 4) The FM Signal with a Modulation index mf is passed through a Frequency Tripler. The Wave is the Out Put of the Tripler will have a modulation Index of Mf 9 Mf 3 Mf 3 Mf 9 Mf 5) In high power AM transmission, Modulation is done at Buffer Stage Oscillator Stage RF Stage IF Stage 6) Vacuum Tube Eventually Fall at Microwave Frequencies Because of their Inter Electrode Capacitance Small Series inductance Large Shunt Capacitance Short Transit Time Increase Noise Figure 7) The Biggest Disadvantage the IMP ATT Diode has is its Low Efficiency High Noise Low BW Inutility to provide Pulse Operation Low Power handling Ability 8) In AM transmission the Frequency, Which is not transmitted is Carrier Frequency Audio Frequency Upper Side Frequency Lower Side Frequency 9) FM Broadcast band lies in VHF UHF SHF HF 10) The Modulation System inherently is most Noise Resistant in SSB Suppressed carrier FM PPM PCM For BSNL TTA JE Exam Paper          |
