Question

1) convert binary number 10.011 into equivalent
decimal number

2) Determine the two's complement of the given binary number
10011100

3) Design a combinational logic circuit that can add 3 bit binary
imputs

Answer #1

A). Convert following decimal integers to 8-bit two's complement
binary numbers using any
method . Explain why, If decimal number cannot be represented
with 8 bits.
a. -46 b. -63 c. 118 d. -128 e. 128
B). Perform following operations by converting the decimal
numbers to 8-bit two’s complement
binary. Check results by converting final result to decimal
a. 94-53 b. 15–84

Assuming nine-bit 2’s complement representation, convert the
decimal number -137 to binary, show the effect of
the ROL operation on it with initial carry C=1,
show the status bits and then convert the result back to decimal.
Repeat with the ASR operation. Write the
RTL specification of both operations shown
here.

EE 263 Homework Assignment 1
Perform the following conversions:
Convert 51 (decimal) to binary and to hex
Convert 0xD1 (hexadecimal) to binary and to decimal
Convert 0b11001001 (binary) to hex and to decimal
Find the 2’s complement of the following 4-bit numbers
1101
0101
Perform the following 4-bit unsigned operations. For
each, indicate the 4-bit result and the carry bit, and indicate if
the answer is correct or not.
5 + 8
2 + 12
13 – 7
4...

Design a sequential circuit that will negate four-bit two's
complement integer. That is if, for example,if the input is 3 (in
two's compliment representation) the output should be -3 (in two's
complement notation). Start with the truth table, next write the
formulas for each output in SOP form, next simplify formulas using
Karnaugh maps and finally draw the simplified circuit.
Thank you

Find the 2's complement of the following decimal numbers (You
must convert the number to binary and the answer has to be in
binary with the same number of bits as the conversion)?
a. 20
b. 15
c. 2126
d. 266
e. 466
please explain how you did it!

The 8-bit signed binary 2's complement number equal to the
decimal number -73 is [a].

a) Do the operation 75.38 - 18.62 in binary
using two's complement. Use for part
fractional 6 bits
b) Convert the resulting expression to decimal, and say how much
is the absolute error obtained in the operation

6. What decimal number does the bit pattern 0xBF800000
represent if it is:
A two's complement integer
An unsigned integer
A floating point number assuming the IEE 754 single
precision format
PLEASE EXPLAIN AND SHOW WORK

I have an 4-bit unsigned Binary adder that performs F=A+B with
carry in and carry out, I have to draw the smallest circuit using
the adder and whatever other combinational logic gates I need to
perform the 4-bit function below on 2's complement numbers A and
B
F=A+B if ADD=1,
F=A-B if ADD=0

1-What is the decimal number of the binary numbers
