In given Combinational logic, X is given by

Each Transistor in Darlington pair (as shown in Fig.) has $$h_{fe} = 100.$$ Overall $$h_{FE}$$ of composite transistor neglecting leakage current is,

In a given network (shown in Figure), a steady state is reached with switch k open. At t = 0, which is closed. Determine the valuesof $$I_1, I_2 and I_3$$ at t = 0+.

Simplify Boolean function represented in sum of product of min-terms,
$$F(x, y, z) = \sum (0, 2, 4, 5, 6)$$

A system described by the transfer function $$H(s) = \frac{1}{s^3 + as^2 + ks + 3}$$ is stable. The constraints on $$\alpha$$ and $$k$$ are

Consider a unity feedback system whose open loop transfer function is $$G(s) = \frac{k}{s(s^2 + 2s + 2)}$$ The Nyquist plot for this system is

Eye Diagram gives an idea of

The signal flow diagram for a certain feedback control system is shown in figure.

Now consider the following set of equations for the nodes

1. $$x2 = a1 \times 1 + a9 \times 3$$
2. $$x3 = a2 \times 2 + a8 \times 4$$
3. $$x4 = a3 \times 3 + a5 \times 2$$
4. $$x5 = a4 \times 4 + a6 \times 2$$

Which of the following are correct?
