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.

What is the definition of parallel adder?
A parallel adder is a binary adder that can possibly form sum and carry the outputs for addend and augend words that operate on corresponding pairs addend and augend bits in parallel.
What is the definition of a parallel adder?
It is a digital circuit that produces the arithmetic sum of two binary number .It can be constructed with the full adders connected in cascade,with the output carry from each full adder connected to the input carry of the next full adder in the chain.

What are the applications of 4 bit adder and subtractor?
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.
How do you design 12 bit binary adder subtractor?
design a one bit slice of the adder subtractor and iterate it through all 12 bits.
How can you use 5 -Bit Adder as a Subtractor?
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.
What are the applications of adder and subtractor?
it can be used in op amp circuits, that is as comparitors or differentiators
Full subtractor using 2 half subtractor?
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.
How full adder convert to full subtractor?
simply by complementing x input before applying to and gate for generating carry

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.
How will 7483 IC operate if C input 0?
The 7483 is a 4 bit full adder and a 0 on C will make it act as a subtractor
Half-Subtractor circuit using NOR gates?
By using 5 NOR gates, we can implements half-subtractor. The inputs for 1st NOR gate are A and B, for 2nd NOR gate inputs are the output of 1st NOR gate and A input, for 3rd NOR gate inputs are the output of 1st NOR gate and B input, for 4th NOR gate the inputs are gates 2 and 3, and for last gate input is the output of the 4th gate.

Difference in 1's and 2's Complement?
1's Complement, has two different codes for the number 0 (+0 & -0), negative numbers are the simple binary complement of positive numbers, is symmetrical (same number of negative and positive numbers can be represented), adder/subtractor must implement wraparound carry from MSB to LSB to get correct answer2's Complement, has only one code for the number 0 (+0), negative numbers are 1 greater than the simple binary complement of positive numbers, is asymmetrical (one extra negative number than positive numbers), adder/subtractor is identical to a simple unsigned binary adder/subtractor without any special carry circuits needed
