What does it mean by amplification?

What does it mean by amplification?

1 : to expand (something, such as a statement) by the use of detail or illustration or by closer analysis. 2a : to make larger or greater (as in amount, importance, or intensity) : increase. b : to increase the strength or amount of especially : to make louder.

What is amplification of signal?

Amplification means increasing the amplitude (voltage or current) of a time-varying signal by a given factor, as shown here. The graph shows the input (blue) and output voltage (red) of an ideal linear amplifier with an arbitrary signal applied as input.

What is a amplification in physics?

(physics) The act, or result of independently increasing some quantity, especially voltage, power or current. The act or result of amplifying, enlarging, or extending.

What do you mean by amplification factor?

Definition of amplification factor : the ratio of the changes in plate and grid voltage that cause equal changes in the plate current of an electron tube.

What does amplification mean in law?

Definition of Terms and Abbreviations Definition of Terms Amplified describes a situation where no change is being made in a prior published position, but the prior position is being extended to apply to a variation of the fact situation set forth therein.

What’s a sentence for amplify?

Amplify sentence example. If you already have a large amount of productivity, technology will amplify it. He and his teachers use microphones to amplify sounds and he has his own sign interpreter. You can turn someone else’s energy into yours and amplify it.

What is amplifier and its types?

Voltage Amplifier: An amplifier that amplifies given voltage for a larger voltage output. Transconductance Amplifier: An amplifier that changes output current according to changing input voltage. Transresistance Amplifier: An amplifier that changes output voltage according to changing input current.

What is an example of amplification?

In literature, amplification means the writer is adding more information to a sentence. For example, “The dog is an excellent breed” can benefit from a bit of amplification. As such, the writer might say, “The dog is an excellent breed, full of intelligence, loyalty, and overall healthfulness.”

What is amplification in geography?

Shaking levels at a site may be increased, or amplified, by focusing of seismic energy caused by the geometry of the sediment velocity structure, such as basin subsurface topography, or by surface topography. View Amplification animation.

What is amplifier and its type?

An amplifier is an electronic device that increases the voltage, current, or power of a signal. Amplifiers are used in wireless communications and broadcasting, and in audio equipment of all kinds. They can be categorized as either weak-signal amplifiers or power amplifiers.

What is the difference between amplification and gain?

It is often expressed using the logarithmic decibel (dB) units (“dB gain”). A gain greater than one (greater than zero dB), that is amplification, is the defining property of an active component or circuit, while a passive circuit will have a gain of less than one.

What is soil amplification factor?

In this study, seismic amplification is measured with an amplification factor (AF), defined as the ratio of response spectra between soil surface and outcropping reference rock. Among many other parameters characterizing the intensity of ground motion, response spectra are the most used in engineering practice.

What is the definition of amplification?

Definition of amplification 1a : an act, example, or product of amplifying b : a usually massive replication of genetic material and especially of a gene or DNA sequence (as in a polymerase chain reaction) 2a : the particulars by which a statement is expanded b : an expanded statement

What is the gain of an amplifier?

The gain of an amplifier is a measure of the “Amplification” of an amplifier, i.e. how much it increases the amplitude of a signal. More precisely it is the ratio of the output signal amplitude to the input signal amplitude, and is given the symbol “A”.

What is an amplifier used for?

An amplifier is used to increase the amplitude of a signal waveform, without changing other parameters of the waveform such as frequency or wave shape. They are one of the most commonly used circuits in electronics and perform a variety of functions in a great many electronic systems.

What is the difference between amplification and increment?

amplification – the amount of increase in signal power or voltage or current expressed as the ratio of output to input. gain. increment, increase – the amount by which something increases; “they proposed an increase of 15 percent in the fare”.
