ELE323 : High Voltage Engineering Practices Question for exams

Questiom 1.

Design a 4-bit full adder using half adders and other combinational logic elements.

Question 2.

 It is desired to design a n-bit binary ripple counter that is capable of counting the number of items passing on a conveyor belt. Each time an item passes a given point, a pulse is generated that can be used as a clock input. If the maximum number of items to be counted is 8000, determine the number of flip-flops required.

Question 3.

Write a program in MATLAB for Double-Sideband  Amplitude Modulation.

Question 4.

Compute the voltage gain G_V and then the output voltage v_out for the inverting op amp circuit shown in Figure below, given that v_in = sin(t) mV. Plot v_inand v_out as mV versus time on the same set of axes.

Question 5.

Compute the output voltage v_out for the amplifier circuit shown below:

Question 6.

Discuss the Inverting and non-inverting modes of operation of op-amp IC-741.
