For the transistor circuit shown in the figure, V_BE = 0.7 V, if β = 80, the value of V_CE is (the V_CE at saturation is 0.2 V)  _____

For a wide band pass filter, if the cut off frequencies are 200 Hz and 1 kHz respectively, evaluate centre frequency and quality factor.

The statistically independent random variables ‘X’ and ‘Y’ have mean value U_x = 2 and U_y = 4. They have second order moments E[X²] = 8 and E[Y²] = 25. What is E[W²] for the random variable W = 3X – Y?

Given the homogenous state-space equation  The steady-state value of  given the initial state value of x(0) = [10 - 10]^T is

A micro-instruction format has micro-ops field which is divided into three subfields F1, F2, F3 each having seven distinct micro-operations, condition field CD for four status bits, branch field BR having four options used in conjunction with address field ADF. The address space is of 128 memory locations. The size of micro-instruction is :

A 5-bit D/A converter has a current output. If an output current I_out = 10 mA is produced for a digital input of 10100, the value of I_out for a digital input of 11101 will be

For the circuit in figure, the values of i₁ and i₄, are respectively,

The fermi-level in n-type silicon at T = 300 K is 230 meV below the conduction band and 200 meV below the donor level. The probability of finding an electron in the donor level is
