Subtractor :
In Electronics Subtractor is a Combinatorial circuit which is used to Subtract two Binary Numbers, x & y.
Half Subtractor :
Half Subtractor is a circuit which is used to Subtract the two bit Binary Numbers.
Full Subtractor :
Full Subtractor is a circuit which is used to Subtract the Two Bit Binary Numbers and a 1 borrowed from Last Lower significant stage.
Hope this answer will help you.....Remember In your Prayers.
simply by complementing x input before applying to and gate for generating carry
The half adder is an example of a simple, functional digital circuit built from two logic gates. A half adder adds two one-bit binary numbers A and B. It has two outputs, S and C (the value theoretically carried on to the next addition); the final sum is 2C + S.
IC 7485 (a comparator) can be used as a subtractor, this is because...... as a 4-bit subtractor calculates the difference between the inputs and then provides value for a borrow and a difference.....in the same way a 4-bit comparator (in this case IC 7485) takes the inputs compares it and gives a corresponding value either A>B or A=B or A

A 5-bit adder can be used as a subtractor by utilizing the concept of two's complement. To perform subtraction, you can invert the bits of the number to be subtracted (the subtrahend) and add 1 to it, effectively converting it to its two's complement. Then, you input this modified value along with the minuend into the 5-bit adder. The result will be the difference of the two numbers, allowing the adder to function as a subtractor.
A half-subtractor lets you borrow out, but not borrow in. A full subtractor is made by combining two half-subtractor and adding an OR-gate. (lets you both BOR_in as well)
Advantage:1:To overcome half subtractor, full subtractor comes into play
-Half subtractor is used to reduce the force of audio or radio signals. -It can be used in amplifiers to reduce the sound distortion. -Half subtractor is used in ALU of processor. -It can be used to increase and decrease operators and also calculates the addresses.
To make a full subtractor, you need an XOR and a NAND gate.

A subtractor can be designed using the same aproach as that of an adder ,subtractor are usually implemented within a binary adder for only a small cost when using the standard two's complement notation,by providing an addition/subtraction sector to the carry in and invert the second operand. A subtractor using of diffrencate bits.
An adder-subtractor is a circuit capable of subtracting or adding binary numbers. The application of a 4-bit adder and subtractor is for use as part of the core of an ALU, or arithmetic logic unit.

The optical signal processing is one of the application of the half subtractor circuit. Binary numbers is another application.
design a one bit slice of the adder subtractor and iterate it through all 12 bits.
The circuit that takes the difference of two signals is called a subtractor. It is made by connecting an inverting amplifier to a two-input inverting averager.
