Constant M- loci:
A. Constant gain and constant phase shift loci of the closed-loop system.
B. Plot of loop gain with the variation in frequency
C. Circles of constant gain for the closed loop transfer function
D. Circles of constant phase shift for the closed loop transfer function
Answer:D
Constant M- loci:
A. Constant gain and constant phase shift loci of the closed-loop system. B. Plot of loop gain with the variation in frequency C. Circles of constant gain for the closed loop transfer function D. Circles of constant phase shift for the closed loop transfer function
Explanation: By definition, Constant M loci are Circles of constant phase shift for the closed loop transfer function.
