Combinational Circuits and Infinite Possibilities.

In summary, a multiple output circuit with 4 inputs and 4 outputs has 2 NOT gates, 4 AND gates, and 1 OR gate. The inputs and outputs go through the gates multiple times, resulting in 11 possible outcomes. Depending on the number of inputs and outputs, there may be an infinite number of possibilities. There are various websites available for learning about combinational circuits.

1. A multiple output circuit has 4 items going into the combinational circuit and 4 lines exiting. However, the map of the circuit has 2(not gates) and 4 and gates and 1 or gate. All of the lines enter and exit all the gates some twice.



2. x1 & x2 start into the one and gate, then go out to 1 y line. This I understand! Easy as pie, but when they both jog into the or gate and through a not gate then back to a and gate..I am so confused.



3. So far I have 11 possible outcomes. Is it feasible to say x1-xn & y1 -yn have infinite possibilities? Could I just say x1, x2, x3, x4 6 ^ (and sign) y1, y2, y3, y4 = infinity?

Anyone know a good site that shows a Combinational Circuit?

Any information would greatly be appreciated! :cry:

Yes, it is possible for x1-xn and y1-yn to have an infinite number of possibilities. However, the exact number of possibilities depends on how many inputs and outputs the circuit has. For example, if the circuit has 4 inputs and 4 outputs, then there are 16 possible combinations of inputs and outputs.There are a number of websites which provide information and diagrams of combinational circuits. Some good ones include: • The Digital Electronics Tutorials website: http://www.digikey.com/en/resources/tutorials/technology-explorer/digital/combinational-logic-circuits• The All About Circuits website: https://www.allaboutcircuits.com/textbook/digital/chpt-3/combinational-logic-circuits/• The Electrical4U website: https://www.electrical4u.com/combinational-logic-circuits/• The Khan Academy website: https://www.khanacademy.org/computing/computer-science/digital-circuits
 

1. What are combinational circuits and how do they work?

Combinational circuits are electronic circuits that perform logical operations on input signals to produce output signals. They are made up of logic gates, which are interconnected to create a desired logic function. The output of a combinational circuit depends only on the current inputs, making them different from sequential circuits which have memory elements.

2. How do combinational circuits differ from sequential circuits?

Combinational circuits are different from sequential circuits in that they have no memory elements and their output depends solely on the inputs. This means that the output of a combinational circuit can be determined at any given moment, while the output of a sequential circuit depends on the current inputs as well as the previous inputs and the internal state of the circuit.

3. What are the different types of combinational circuits?

There are several types of combinational circuits, including adders, subtractors, multiplexers, demultiplexers, encoders, decoders, and comparators. Each type performs a specific logical function and can be combined to create more complex circuits.

4. What are some real-world applications of combinational circuits?

Combinational circuits have a wide range of applications in various fields, including computer science, telecommunications, and control systems. Some common examples include calculators, digital clocks, traffic light controllers, and data encryption systems.

5. Can combinational circuits have infinite possibilities?

No, combinational circuits cannot have infinite possibilities because they are made up of a finite number of logic gates and inputs. However, they can have a large number of possible combinations, which can be increased by adding more inputs or logic gates to the circuit.
