Question

I
need to create two 4 bit adders (ic 7483) with a ic(7447) attached
to a 7 segment display. any chance someone can draw up the circuit
diagram or explain to me how this is setup?

Answer #1

Design a 4-bit adder-subtractor circuit using the 4-bit binary
Full adders (74LS83) and any necessary additional logic gates. The
circuit has a mode input bit, M, that controls its operation.
Specifically, when M=0, the circuit becomes a 4-bit adder, and when
M=1, the circuit becomes a 4-bit subtractor that performs the
operation A plus the 2’s complement of B.Where A and B are two
4-bits binary numbers. That is,
* When M=0, we perform A+B, and we assume that
both...

Please clearly show and explain how I am to do this:
Using TinkerCad or the Arduino kit, create a circuit using a
keypad and one 7-segment display. When you press any key on the
keypad it must be displayed on the 7-segment display. Due to the
limited number of pins on the Uno (TinkerCad) you must use the
Analog Pins as Digital inputs.

I am designing an 8 bit calculator on Logisim and am having
difficulty with the final display. I need to convert an 8 bit
result to display onto two hex digit displays. Each display has 2
inputs. 1 for the 4 bit binary that is converted to hex on the
display and one controls the decimal point. Please explain the best
way to display my result on these to displays.
Thanks!

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

Design a circuit for a synchronous 4-bit counter. Your counter
should count up starting from 0 to 9 (00002
to 10012)
and then wind back to 0 (00002)
–
after 9, it should go back to 0.
Use 4 JK flip-flops and any other gates you need. Include your
design documentation in your submission:
a.
Truth table
b.
Simplification (show your work)
2.
Build this circuit in
Logisim.
Please label each gate, including flip-flops. You may need the
following wiring...

How
could I create a very basic assembly program that is able to use
string literals, reserved words, and identifiers? I also need to
process some directives, instructions, and labels as well. Could
someone generate a simple assembly program to do these things?
Thank you!
My
apologies, x86 processors. It's also a 32-bit program!
We
are using Visual Studio, and writing 32-bit programs. This program
can literally do anything, as long as it meets the following
requirements as described above.

Adder
Start out by picking 2 positive six bit binary numbers that are
less than 3210, written in 2's complement notation. The
eventual goal is to add these two numbers.
1) Look at the LSB bit of the numbers, and using logic gates
(NANDs, NORs, etc.) design a circuit that correctly gives the right
output for any possible combination of bits in the LSB place.
2) Now look at the next column to the left (next to LSB). In
this...

Hi! i need to calculate the Ka for acetic acid from an
experiment using an ice diagram but my Ka value keeps coming up
negative. I'm using the pH of the acetic acid before titration with
NaOH (pH = 2.96) to get [H3o+] and [OAc] to equal 10^(-2.96) which
is 1.1x10-3. And the moles of acid in my original flask was 0.004
HOAc, so can someone show me the calculations if I am doing them
wrong or help me figure...

Part 1
I need to make an example class that I make up on my own. It
should have some variables, at least one function and at least one
procedure in it. And then I should create two instances of the
class and demonstrate how to use the class by calling some of the
procedures and functions. What I make my class about is up to
me.
Part 2
Do a simple example of ByVal vs ByRef. I can do...
