What is subtractor with the circuit diagram briefly explain different types of subtractor?

subtractor An electronic logic circuit for calculating the difference between two binary numbers, the minuend and the number to be subtracted, the subtrahend (see table). A full subtractor performs this calculation with three inputs: minuend bit, subtrahend bit, and borrow bit.

What is subtractor and its types?

Subtractor circuits take two binary numbers as input and subtract one binary number input from the other binary number input. Similar to adders, it gives out two outputs, difference and borrow (carry-in the case of Adder). There are two types of subtractors. Half Subtractor. Full Subtractor.

What is subtractor with the circuit diagram?

A full subtractor is a combinational circuit that performs subtraction of two bits, one is minuend and other is subtrahend, taking into account borrow of the previous adjacent lower minuend bit. This circuit has three inputs and two outputs.


What are the two types of basic subtractor circuit Mcq?

What are the two types of basic adder circuits? Explanation: There are two types of adder circuits: half-adder and full-adder. Half-Adder has 2 inputs while Full-Adder has 3 inputs. Whereas, both have two outputs SUM and CARRY.

What is half subtractor and full subtractor explain?

The Half Subtractor is used to subtract only two numbers. To overcome this problem, a full subtractor was designed. The full subtractor is used to subtract three 1-bit numbers A, B, and C, which are minuend, subtrahend, and borrow, respectively.


Full Subtractor | Easy Explanation



What is full subtractor?

The full subtractor is a combinational circuit which is used to perform subtraction of three input bits: the minuend , subtrahend , and borrow in . The full subtractor generates two output bits: the difference and borrow out .

What are the two types of basic subtractor circuits?

There are two types of subtractors.
  • Half Subtractor.
  • Full Subtractor.


How many types of registers are Mcq?

How many types of registers are? Explanation: There are 4 types of shift registers, viz., Serial-In/Serial-Out, Serial-In/Parallel-Out, Parallel-In/Serial-Out and Parallel-In/Parallel-Out.

What is the difference expression if A and B and C are inputs of a full subtractor?

Explanation: The sum and difference output of a full adder and a full subtractor are same. If A, B and C are the input of a full adder and a full subtractor then the output will be given by (A XOR B XOR C), respectively.


What are parallel adders and subtractors?

The parallel adder/subtractor performs the addition operation faster as compared to serial adder/subtractor. Time required for addition does not depend on the number of bits. The output is in parallel form i.e all the bits are added/subtracted at the same time.

What is 4 bit subtractor?

In Digital Circuits, A Binary Adder-Subtractor is one which is capable of both addition and subtraction of binary numbers in one circuit itself. The operation being performed depends upon the binary value the control signal holds. It is one of the components of the ALU (Arithmetic Logic Unit).

What do you mean by binary subtractor?

As their name implies, a Binary Subtractor is a decision making circuit that subtracts two binary numbers from each other, for example, X – Y to find the resulting difference between the two numbers.

How many types of logic gates does a full subtractor have?

Likewise, the full-subtractor uses binary digits like 0,1 for the subtraction. The circuit of this can be built with logic gates such as OR, Ex-OR, NAND gate. The inputs of this subtractor are A, B, Bin and outputs are D, Bout.


What is half subtractor?

Half Subtractor is a combinational logic circuit. It is used for the purpose of subtracting two single bit numbers. It contains 2 inputs and 2 outputs (difference and borrow).

What is op amp subtractor?

An op-amp based subtractor produces an output equal to the difference of the input voltages applied at its inverting and non-inverting terminals. It is also called as a difference amplifier, since the output is an amplified one.

Why it is called Half subtractor?

Quite similar to the half adder, a half subtractor subtracts two 1-bit binary numbers to give two outputs, difference and borrow. Since it neglects any borrow inputs and essentially performs half the function of a subtractor, it is known as the half subtractor.

What is the difference between full adder and full subtractor?

When designed from truth-tables and K-maps, a full subtractor is very similar to a full adder, but it contains two inverters that a full adder does not. When configured to subtract, an adder/subtractor circuit adds a single inverter (in the form of an XOR gate) to one input of a full adder module.


What is the difference between adder and subtractor circuits?

When M= 1, the circuit is a subtractor and when M=0, the circuit becomes adder. The Ex-OR gate consists of two inputs to which one is connected to the B and other to input M. When M = 0, B Ex-OR of 0 produce B. Then, full adders add the B with A with carry input zero and hence an addition operation is performed.

What are the different types of registers?

Types of Register in Computer Organization
  • AC ( accumulator )
  • DR ( Data registers )
  • AR ( Address registers )
  • PC ( Program counter )
  • MDR ( Memory data registers )
  • IR ( index registers )
  • MBR ( Memory buffer registers )


What is the difference between shift right register and shift left register Mcq?

What is the difference between a shift-right register and a shift-left register? Explanation: In shift-right register, shifting of bit takes place towards the right and towards left for shift-left register. Thus, both the registers vary in the shifting of their direction. 3.

What are half adders and full adders?

The Half Adder is a type of combinational logic circuit that adds two of the 1-bit binary digits. It generates carry and sum of both the inputs. The Full Adder is also a type of combinational logic that adds three of the 1-bit binary digits for performing an addition operation.


What is the difference between combinational and sequential circuits?

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 full adder and subtractor explain?

In digital circuits, an adder–subtractor is a circuit that is capable of adding or subtracting numbers (in particular, binary). Below is a circuit that adds or subtracts depending on a control signal. It is also possible to construct a circuit that performs both addition and subtraction at the same time.

What is the requirement of full subtractor circuit Mcq?

D. Explanation: a full subtractor has 3 input bits and two outputs bits borrow and difference.
