Question

Select all correct answers: what are the key differences between combinational and sequential logic/circuits?

1. Outputs of sequential circuit depend solely on current input values
2. Outputs of sequential circuit depend solely on past t input values
3. sequential circuit can have memory
4. sequential circuit cannot have memory
5. Outputs of combinational circuit depend solely on current input values
6. Outputs of combinational circuit depend solely on past input values
7. Combinational circuits can have memory 8. Combinational circuits cannot have memory

Answer 1

The correct answers are:

1. Outputs of sequential circuit depend solely on current input values

3. sequential circuit can have memory

5. Outputs of combinational circuit depend solely on current input values

8. Combinational circuits cannot have memory

Step-by-step explanation:

Combinational circuits produce an output based solely on the current input values, without any regard for past input values or previous circuit behavior. These circuits do not have any memory element.

On the other hand, sequential circuits produce an output based on both the current input values and past input values, which are stored in some form of memory element. Therefore, sequential circuits have memory and produce output based on the input and the state of the circuit.

So, options 2, 4, 6, and 7 are incorrect.
