## Control Systems Weighting function is in terms of -----------------

Laplace transform of the parabolic response
Laplace transform of the ramp response
Laplace transform of the impulse response
Laplace transform of the step response

## Control Systems Which of the following combinations is/are correct electrical analogous elements in force-current analogy?

Velocity (v) ----------------- Voltage (V)
Force (f) --------------------- Current (i)
Spring element (K) --------- Inverse inductance (1/L)
All of these

## Control Systems For a transfer function H (s) = P(s) / Q(s), where P (s) and Q (s) are polynomials in s. Then

the degree of P (s) and Q (s) are same.
maximum degree of P (s) and Q (s) differ at most by one.
degree of P (s) is independent of degree of Q (s).
the degree of P (s) is always greater than the degree of Q (s).
