Which one of the following statement is correct regarding constant N circles ?

Which one of the following statement is correct regarding constant N circles ? Correct Answer The locus of constant, closed-loop phase frequency response for unity feedback systems.

Solution:

  • Constant magnitude loci that are M-circles and constant phase angle loci that are N-circles are the fundamental components in designing the Nichols chart.
  • The constant M and constant N circles in G (jω) plane can be used for the analysis and design of control systems.
  • N- circles are used to determine the phase response of a closed-loop system using the open-loop transfer function.
