Question
The transfer function of a system is given by,Let the output of the system be for the input, . Then the minimum and maximum values of (in radians) are respectively
Correct answer
(D) -π and 0
Solution
The transfer function is . For a sinusoidal input at frequency , the phase shift is given by the phase of :As varies from to :
1.At , .
2.As , .
Thus, the range of is . The minimum value is and the maximum value is .Continue learning with Success Tracker
