Question

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.

(a) Both A and R are true but R is correct explanation of A

(b) Both A and R are true but R is correct explanation of A

(c) A is true but R is false

(d) A is false but R is true

The question was asked in an internship interview.

Asked question is from Bode Plots in chapter Frequency Response Analysis of Control Systems

Answer 1

Right choice is (b) Both A and R are true but R is correct explanation of A

Explanation: Transportation lag can be conveniently handled on Bode plot as well without the need to make any approximation.
