## What is combinational and sequential circuit?

The combinational circuit is time-independent. The output it generates does not depend on any of its previous inputs. On the other hand, sequential circuits are the ones that depend on clock cycles. They depend entirely on the past as well as the present inputs for generating output.

**What is the difference between combinational and sequential logic?**

The main difference between them is that the Combinational circuit generates output depending only on the present given input, and sequential circuits use present input and present state (previous output) to generate the present output.

**What is difference between combinational circuit and sequential circuits PDF?**

Combinational circuits are defined as the time independent circuits which do not depends upon previous inputs to generate any output are termed as combinational circuits. Sequential circuits are those which are dependent on clock cycles and depends on present as well as past inputs to generate any output.

### What are combinational and sequential circuits with examples?

Examples of combinational circuits are a half adder, full adder, magnitude comparator, multiplexer, demultiplexer, etc. Examples of sequential circuits are flip-flop, register, counter, clocks, etc.

**What is combinational circuit with example?**

A Combinational Circuit consist of logic gates whose outputs at any instant of time are determined directly from the present combination of inputs without regard to previous input. Examples of combinational circuits: Adder, Subtractor, Converter, and Encoder/Decoder.

**What is combinational logic and sequential logic?**

A combinational circuit consists of logic gates whose outputs at any time are determined from only the present combination of inputs and they have no memory. A sequential circuit consists of logic gates whose outputs at any time are determined from both the present combination of inputs and previous output.

#### What do you mean by combinational logic?

In automata theory, combinational logic (also referred to as time-independent logic or combinatorial logic) is a type of digital logic which is implemented by Boolean circuits, where the output is a pure function of the present input only.

**What is the difference between combinational logic and sequential logic Mcq?**

10. What is the difference between combinational logic and sequential logic? A. Combinational circuits are not triggered by timing pulses, sequential circuits are triggered by timing pulses.

**Which is combinational logic circuit?**

A combinational circuit is the digital logic circuit in which the output depends on the combination of inputs at that point of time with total disregard to the past state of the inputs. The digital logic gate is the building block of combinational circuits.

## What are the two types of sequential circuits?

There are two types of sequential circuit, synchronous and asynchronous. Synchronous types use pulsed or level inputs and a clock input to drive the circuit(with restrictions on pulse width and circuit propagation). Asynchronous sequential circuits do not use a clock signal as synchronous circuits do.

**What are combinational circuits types?**

There are different types of combinational logic circuits, such as Adder, Subtractor, Decoder, Encoder, Multiplexer, and De-multiplexer.

**What is the difference between sequential and combinational circuits Mcq?**

Combinational circuits are the ones which do not depend on previous inputs while Sequential circuits depend on past inputs.

### What are the types of combinational circuits?

**What is the difference between combinational logic and sequential logic Sanfoundry?**

Explanation: In a combinational circuit, the output at any time depends only on the input values at that time and not on past or intermediate values. 4. In a sequential circuit, the output at any time depends only on the input values at that time.
