## What is subtractor in digital system?

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 the subtractor called?

The number which we subtract from another number in a subtraction sentence is called a subtrahend. Subtrahend is the second number in a subtraction sentence. It is subtracted from the minuend to get the difference.

### What is adder and subtractor in digital electronics?

In digital circuits, an adderâ€“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 function of full subtractor?

The full subtractor is used to subtract three 1-bit numbers A, B, and C, which are minuend, subtrahend, and borrow, respectively. The full subtractor has three input states and two output states i.e., diff and borrow.

What are the applications of subtractors?

Subtractors are mostly used for performing arithmetical functions like subtraction, in electronic calculators as well as digital devices. Subtractors are used in processors to compute tables, addresses, etc. It is also useful for DSP and networking based systems.

## How many types of subtractors are there?

There are two types of subtractors. The half-subtractor is a combinational circuit which is used to perform subtraction of two bits. It has two inputs, X (minuend) and Y (subtrahend) and two outputs D (difference) and B (borrow). The logic symbol and truth table are shown below.

What are the applications of Subtractors?

How many types of Subtractors are there?

### What is subtractor amplifier?

The Subtractor also called a differential amplifier, uses both the inverting and non-inverting inputs to produce an output signal which is the difference between the two input voltages V1 and V2 allowing one signal to be subtracted from another. More inputs can be added to be subtracted if required.

What are the two types of basic subtractor circuits?

There are two types of subtractors.

• Half Subtractor.
• Full Subtractor.
