If the Nyquist plot does not encircle the (-1 + j0) point the system is always stable.
Assertion (A): When the phase margin of a control system is improved using a lead network, noise transmission increases. Reason (R): Phase lead compensation increases bandwidth.
Assertion (A): A slight change in pole-zero configuration can cause only minor changes in root locus configuration. Reason (R): Asymptotes show the behaviour of root loci for |s| >> 1
The constant magnitude of G(s) plane are
Assertion (A): Integration in time domain is converted into division in s domain Reason (R):
Assertion (A): In an automobile the amount of fuel admitted to the engine is adjusted as per the difference between desired and actual speed. Reason (R): The control signal is the amount of fuel to be admitted to the engine.
ssertion (A): The steady state response, of a stable, linear, time invariant system, to sinusoidal input depends on initial conditions. Reason (R): Frequency response, in steady state, is obtained by replacing s in the transfer function by j
A system has its two poles on the negative real axis and one pair of poles lies on j axis. The system is
