Instrumentation-FREQUENCY RESPONSE ANALYSIS part 2 Leave a Comment / By Areej / March 5, 2018 November 11, 2020 Welcome to your Quiz .This quiz is about FREQUENCY RESPONSE ANALYSIS .it contains 10 questions 1. Assertion (A): Relative stability of the system reduces due to the presence of transportation lag. Reason (R): Transportation lag can be conveniently handled by Bode plot. Both A and R are true but R is correct explanation of A Both A and R are true but R is correct explanation of A A is true but R is false A is false but R is true 2. What is the value of M for the constant M circle represented by the equation 8x^2+18x+8y^2+9=0? 0.5 2 3 8 3. Consider the following statements: Nichol’s chart gives information about. i. Closed loop frequency response. ii. The value of the peak magnitude of the closed loop frequency response Mp. iii. The frequency at which Mp occurs. Which of the above statements are correct? 2 and 3 1 and 2 1 and 3 1,2 and 3 4. Which one of the following statements is correct? Nichol’s chart is useful for the detailed study analysis of: Closed loop frequency response Open loop frequency response Close loop and open loop frequency responses None of the above 5. In a bode magnitude plot, which one of the following slopes would be exhibited at high frequencies by a 4th order all-pole system? -80dB/decade -40 dB/decade 40 dB/decade 80 dB/decade 6. All the constant N-circles in G planes cross the real axis at the fixed points. Which are these points? -1 and origin Origin and +1 -0.5 and 0.5 -1 and +1 7. The constant M-circle represented by the equation x^2+2.25x+y^2=-1.25 has the value of M equal to: 1 2 3 4 8. A system has poles at 0.01 Hz, 1 Hz and 80Hz, zeroes at 5Hz, 100Hz and 200Hz. The approximate phase of the system response at 20 Hz is : -90° 0° 90° -180° 9. The constant N loci represented by the equation x^2+x+y^2=0 is for the value of phase angle equal to: -45° 0° 45° 90° 10. Assertion (A): The phase angle plot in Bode diagram is not affected by the variation in the gain of the system. Reason(R): The variation in the gain of the system has no effect on the phase margin of the system. Both A and R are true but R is correct explanation of A Both A and R are true but R is correct explanation of A A is true but R is false A is false but R is true Time's up
