QUESTION: 7

The value of input frequency is required to cause a gain equal to 1.5. The value is

Solution:



For any value of ω, R,C gain ≤ 1.
Thus (D) is correct option.

QUESTION: 8

In the circuit of fig. P1.11.18 phase shift equal to -45is required at frequency ω = 20 rad/s . The value of R is

Solution:


QUESTION: 9

For the circuit of fig. P1.11.19 the input frequency is adjusted until the gain is equal to 0.6. The value of the frequency is

Solution:


QUESTION: 10

Bode diagram of the network function Vo/Vs for the circuit of fig. P1.11.30 is

Solution:


-20 dB/decade line starting from ω = 5.56 rad s 20 dB/decade line starting from ω = 16.67 rad s Hence -20 dB/decade line for 5.56 < ω < 16.67 parallel to ω axis to ω > 16.67
