Question

The Routh-Hurwitz criterion cannot be applied when the characteristic equation of the system contains any coefficients which is :

(a) Negative real and exponential function

(b) Negative real, both exponential and sinusoidal function of s

(c) Both exponential and sinusoidal function of s

(d) Complex, both exponential and sinusoidal function of s

Answer 1

Right answer is (b) Negative real, both exponential and sinusoidal function of s

The best explanation: The Routh-Hurwitz criterion cannot be applied when the characteristic equation of the system contains any coefficients which is negative real, both exponential and sinusoidal function of s.
