The op-amps in the following circuit are ideal. The voltage gain of the circuit is ……….. . (Round off to the nearest integer)
The maximum percentage error in the equivalent resistance of two parallel connected resistors of 100 ohm and 900 ohm, with each having a maximum 5% error, is:
A controller \( (1 + K_{DS}) \) is to be designed for the plant \[ G(s) = \frac{1000 \sqrt{2}}{s(s + 10)^2} \] The value of \( K_D \) that yields a phase margin of 45 degrees at the gain cross-over frequency of 10 rad/sec is ……… (round off to 1 decimal place).
Consider the state-space model:
\[ \dot{x}(t) = A x(t) + B u(t) \] \[ y(t) = C x(t) \] \[ A = \begin{bmatrix} 0 & 1 \\ -2 & -3 \end{bmatrix}, \quad B = \begin{bmatrix} 0 \\ 1 \end{bmatrix}, \quad C = \begin{bmatrix} 1 & 0 \end{bmatrix} \]The sum of the magnitudes of the poles is:
