Homework Statement
Circuit:
A B G D E F C
0 0 1 1 1 1 0
1 1 0 1 0 1 0
0 0 1 1 1 1 0
1 1 0 1 0 1 0Answer:
Is (a) right? And any ideas what could be (b)?
You mean I should have four columns?jedishrfu said:Your A and B columns should show all possible values {00, 01, 10, 11}
The output of the D NAND gate is: A' NAND B = (A' & B)' = D
and the F NAND gate is: A NAND B' = (A & B')'
A B
-- --
0 0
0 1
1 0
1 1
But how did you derive these numbers? My original 0101 in A and B I got from the inverter table. But I don't see how to get the ones you mention.jedishrfu said:No, you still have an A and a B column:
Code:A B -- -- 0 0 0 1 1 0 1 1
I get it now.jedishrfu said:Your A and B inputs can be any binary value so since you have two inputs you have a possibility of 4 input values to the circuit as shown in the table above.
A B G D E F C
0 0 1 1 1 1 0
0 1 1 0 0 1 1
1 0 0 1 1 0 1
1 1 0 1 0 1 0
But what could be said about (b)? No idea about it.jedishrfu said:That's what I got too. The circuit diagram has a symmetry about it which is seen in the truth table.
AND has 0001 at outputjedishrfu said:Look at the A and B inputs and then the C output doesn't that look like some gate you're familiar with?
EXOR gate fits the output.insightful said:There is one more basic gate (or two, if you include its negative):

Logic gates are electronic devices that perform logical operations on one or more binary inputs to produce a single binary output. They work by using Boolean logic, which involves the use of logical operators such as AND, OR, and NOT to manipulate binary signals.
There are seven basic types of logic gates: AND, OR, NOT, NAND, NOR, XOR, and XNOR. Each type has a unique function and can be combined to create more complex logical circuits.
A truth table is a table that shows all the possible inputs and their corresponding outputs for a logic gate circuit. To create a truth table, start by listing all the possible combinations of inputs. Then, use the logical operators of the specific gate to determine the output for each input combination.
The truth table is used to determine the output of a logic gate circuit for all possible input combinations. It helps in analyzing the behavior of the circuit and identifying any errors or inconsistencies in the logic.
Logic gates and truth tables are essential tools in digital circuits, which are used in various electronic devices, such as computers, smartphones, and calculators. They can be used to design and troubleshoot circuits in these devices, making them integral to the field of electrical engineering and computer science.
