Q. Scientist Nyquist have contribution in:
  • (A) asymptotic plots
  • (B) polar plots
  • (C) root locus technique
  • (D) constant m and n circle
💬 Discuss
✅ Correct Answer: (B) polar plots

Explanation: nyquist plot is used to find the stability of the system by open loop poles and zeroes and the encirclements of the poles and zeroes and satisfying the equation n=p-z and this is named under the name of scientist nyquist.
