# What is the subtractor?

The half subtractor is a combinational circuit which is used to perform subtraction of two bits. It has two inputs, the minuend and subtrahend and two outputs the difference and borrow out .

What do you mean by full subtractor?

Full subtractor is a combinational circuit capable of performing subtraction on two bits namely minuend and subtrahend. It accepts three inputs: minuend, subtrahend and a borrow bit. It produces two outputs: difference and borrow.

What is a 4 bit full adder?

Sum (Σ) outputs are provided for each bit and a resultant carry (C4) is obtained from the fourth bit. This adder features full internal look ahead across all four bits. A 4 x n binary adder is easily built up by cascading without any additional logic.

## What is meant by excess 3 code?

12. The Excess-3 code:- It is an important BCD code , is a 4 bit code and used with BCD numbers To convert any decimal numbers into its excess- 3 form ,add 3 to each decimal digit and then convert the sum to a BCD number As weights are not assigned, it is a kind of non weighted codes.

## What is the gain of a subtractor op amp?

There’s a special op amp circuit —a differential amplifier, or subtractor — that is actually a combination of a noninverting amplifier and inverting amplifier. A differential amplifier multiplies the difference between two voltages. Here is an op amp subtractor.

## What is the Subtrahend in math?

The first number in a subtraction. The number from which another number (the Subtrahend) is to be subtracted. minuend − subtrahend = difference. Example: in 8 − 3 = 5, 8 is the minuend.

## What is a decoder in digital circuits?

In digital electronics, a binary decoder is a combinational logic circuit that converts binary information from the n coded inputs to a maximum of 2n unique outputs. They are used in a wide variety of applications, including data demultiplexing, seven segment displays, and memory address decoding.

## What is the op amp?

An operational amplifier (or an op-amp) is an integrated circuit (IC) that operates as a voltage amplifier. An op-amp has a differential input. That is, it has two inputs of opposite polarity. An op-amp has a single output and a very high gain, which means that the output signal is much higher than input signal.

## What is op amp and its application?

Op amps are used in a wide variety of applications in electronics. Some of the more common applications are: as a voltage follower, selective inversion circuit, a current-to-voltage converter, active rectifier, integrator, a whole wide variety of filters, and a voltage comparator.

## What is the use of an op amp?

Operational amplifiers. Amplifiers are devices which take a relatively weak signal as an input and produce a much stronger signal as an output. The operational amplifier (or op-amp) is a special kind of amplifier used in equipment such as stereo equipment and medical cardiographs (which amplify the heart beat).

## What is an integrator circuit?

The operational amplifier integrator is an electronic integration circuit. Based on the operational amplifier (op-amp), it performs the mathematical operation of integration with respect to time; that is, its output voltage is proportional to the input voltage integrated over time.

## What is a differentiator op amp?

Op amp differentiator basics. A differentiator circuit is one in which the voltage output is directly proportional to the rate of change of the input voltage with respect to time. This means that a fast change to the input voltage signal, the greater the output voltage change in response.

## What is an integrator and differentiator?

REVIEW: A differentiator circuit produces a constant output voltage for a steadily changing input voltage. An integrator circuit produces a steadily changing output voltage for a constant input voltage.

## What is a differentiator amplifier?

In electronics, a differentiator is a circuit that is designed such that the output of the circuit is approximately directly proportional to the rate of change (the time derivative) of the input. An active differentiator includes some form of amplifier.

## Why is the differentiator called a high pass filter?

The High-pass RC circuit is also known as a differentiator. The name high pass is so called because the circuit blocks the low frequencies and allows high frequencies to pass through it. It is due to reason that reactance of the capacitor decreases with the increasing frequency.

## What is passive high pass filter?

Passive High Pass Filter. A High Pass Filter is the exact opposite to the low pass filter circuit as the two components have been interchanged with the filters output signal now being taken from across the resistor.

## Why LC filter is used?

LC circuits are used either for generating signals at a particular frequency, or picking out a signal at a particular frequency from a more complex signal; this function is called a bandpass filter. The purpose of an LC circuit is usually to oscillate with minimal damping, so the resistance is made as low as possible.

## What is the purpose of an inductor in a circuit?

An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a magnetic field in the clockwise direction.

## What is the meaning of LC oscillators?

LC oscillator is a type of oscillator where a LC (inductor-capacitor) tank circuit is used for giving the required positive feedback for sustaining the oscillations. The LC tank circuit is also termed as LC resonant circuit or LC tuned circuit.
