**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

**and then the output voltage v**_{V}**for the inverting op amp circuit shown in Figure below, given that v**_{out}**= sin(t) mV. Plot v**_{in }**and v**_{in}**as mV versus time on the same set of axes.**_{out}**Question 5.**

Compute the output
voltage v

**for the amplifier circuit shown below:**_{out}**Question 6.**

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