In the figure shown, assume the op-amp to be ideal. Which of the alternatives gives the correct Bode plots for the transfer function $\frac{V_0\left(\omega \right)}{V_1\left(\omega \right)}$ ?

An output device is interfaced with an 8-bit microprocessor 8085A. The interfacing circuit is shown in figure



The interfacing circuit makes use of a 3 Line to 8 Line decoder having 3 enable lines E₁,E̅₂,E̅₃. The address of the device is

The figure shows the circuit diagram of a rectifier. The load consists of a resistance 10Ω and an inductance 0.05H connected in series Assuming ideal thyristor and ideal diode, the thyristor firing angle (in degree) needed to obtain an average load voltage of 70V is __

Figure (i) shows the circuit diagram of a chopper. The switch s in the circuit in the figure (i) is switched such that the voltage V${}_D$ across the diode has the waveshape as shown in the figure (ii). The capacitance C is large so that the voltage across it is constant. If the switch s and diode d are ideal

The peak to peak ripple (in A) in the inductor current is-

The figure shows one period of the output voltage of an inverter, should be chosen such that $60^{\circ }<\alpha <90^{\circ }$. If the rms value of the fundamental component is $50V$, then α in degree is
