PROGRAM- BCA(REVISED FALL 2012)
SEMESTER- I
SUBJECT CODE & NAME
Bt0064
 - DIGITAL LOGIC

Qus:1 Convert the following:
i) (0100 1111 1011 0010)2 to octal number and decimal number
ii) (6704)8 to decimal and binary number
Answer:
i)                    (0100 1111 1011 0010)2 to octal number and decimal number:

Conversion of i)                (

Qus:2 Construct the following gates using NOR gates.
a)XOR
b) NAND
c) XNOR
Answer:
a)      XOR:


Q3. Simplify the following truth table using k-map and find the reduced function f(x,y,z).
x y z    f(x,y,z)
0 0 0    1
0 0 1    1
0 1 0    1
0 1 1    1
1 0 0    0
1 0 1    0
1 1 0    1
1 1 1    1

Answer.

If we have a truth table for a function,we can write a sum of minterms expression just by picking out the rows of the table where the function output is 1.


Q4. Draw the truth table of full adder and implement it using the logic gates.
Answer.

This type of adder is a little more difficult to implement than a half-adder. The main difference between a half-adder and a full-adder is that the full-adder has three inputs and two outputs. The first two inputs are A and B and the


Qus:5 What are sequential circuits? Explain differences between sequential circuits and combinational circuits.

Answer:

Sequential circuits:

Both combinational circuits such as universal gates and memory such as latches and flip flops are used to construct a digital system. In many sequential circuits (like counter and shift registers), MSI, and LSI packages we can see the interconnection of both logic gates and memory elements.


Qus:6 What are shift registers? Explain serial in serial out shift register.

Answer:

Shift registers:
Shift Register is a set of binary storage elements, typically flip-flops combined and linked together to facilitate the movement of the data bits stored, from one to another and in and out of it, whenever desired by activating control signals.Inputs to the shift registers can be serial or parallel.
