Answer: Option B Explanation:
|
converges, then the series 
converges absolutely is| 22. | Open loop transfer function of a system is |
|||||||
Answer: Option B Explanation: GH = - tan- 1 ω - tan- 1 2ω - tan- 1 3ω = - p tan- 1 ω + tan- 1 2ω = p - tan- 1 3ω tan- l
ω = 1 rad/sec. |
= | 23. | The two numbers represent in signed 2's complement form are P = 11101101 and Q = 111001110. If Q subtracted from P, the value obtained in signed 2's complement form is |
|||||||
Answer: Option C Explanation: P = 11101101 = - 25 Q = 11100110 = - 18 Thus P - Q = - 25 - (- 18) = - 7 Thus '- 7's two complement representation is 11111001. |
| 24. | The transfer function |

Answer: Option B Explanation:
|
of an RLC circuit is given by 
quality factor (Q-factor) of this circuit is :
.| 25. | Consider the circuit shown below of 2 : 1 MUX is given by the function g = ac + bc |
|||||||
Answer: Option B Explanation: Since g = ac + bc i.e. when c = 0, g = b and c = 1, g = a Now we evaluate f = (E)(X) + (0)(X) = EX f = (X)(Y) + (EX)(Y) = XY + EXY. |
