And sometimes we sew words together with the finesse of a seamstress to form a sentence. That was an example of amplification. Amplification is the way a writer embellishes a sentence in order to emphasize or exaggerate certain points. In general, amplification involves making something stronger or louder.

What do you mean by 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 amplification principle?
The principle of the amplifier is to produce an output signal that is a replica of the input signal with increased magnitude.
What is meant by amplification in electronics?
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 amplification in waves?
For instance, when a sound wave is amplified, the volume of the sound is increased. The act of increasing signal strength is called amplification, and the measure of that strength is referred to as amplitude.
Does amplification mean increase?
1 : to make louder or greater A megaphone amplifies your voice.
What is amplification Class 11?
Amplification refers to increasing the amplitude and hence the output power of a signal.
What is the current amplification factor?
Current amplification factor in C-E Mode (ฮฒ): The current amplification factor or current gain in C-E mode is defined as the ratio of the change in the collector current (ฮIC) to the change in base current (ฮIB) at a constant collector-emitter voltage (VCE) It has a value between 20 to 500.
How do you write amplify?
- Identify the important details of a statement or parts of a story.
- Elaborate on those details or parts by amplifying them, or extending that section.
What is amplification in sound?
Sounds can be made louder or amplified in a number of ways. By providing more energy in making the sound its loudness can be increased. This would be achieved by beating a drum with greater vigour, blowing harder on the recorder or using more bodily energy in shouting louder.
What is amplification in engineering?
amplification in Electrical Engineering Amplification is the procedure of expanding the strength of a signal. The nonlinear behavior of these components and their ability to control electron flows makes amplification of weak signals possible, and is usually applied to information and signal processing.
What are the 3 types of amplifiers?
Classification of the amplifier can be done in 3 different ways. Voltage amplifiers. Current amplifiers. Power amplifiers.
What is amplifier class12?
An amplifier is a generic term used to describe a circuit that produces an increased version of its input signal or we can say that the circuit or device which can amplify the given input signal.
Why do we need amplifier?
An amplifier’s job is to increase the power output of your source to the level you want, and if whatever you’re using to listen to music can do that on its own: a lack of power isn’t one of your issues. You can stop reading here and go enjoy your audio adventures! If your audio sounds bad, it’s due to something else.
Which is an amplifying device?
Transistor is used as an amplifying device.

What causes wave amplification?
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.
How is amplification obtained?
Amplifier gain is simply the ratio of the output divided-by the input. Gain has no units as its a ratio, but in Electronics it is commonly given the symbol “A”, for Amplification. Then the gain of an amplifier is simply calculated as the “output signal divided by the input signal”.
What is amplitude physics?
amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.
What is the unit of amplification?
Amplification factors are usually expressed in terms of power . The decibel (dB), a logarithmic unit, is the most common way of quantifying the gain of an amplifier.
How do you amplify voltage?
A small AC voltage at the transistor base generates a small base-emitter current which is amplified by the transistor to give a larger AC collector current. This amplified collector current through the collector resistor creates an AC voltage that is greater than the input voltage, thus the input voltage is amplified.
What is amplifier BYJU’s?
Amplifier is an electronic device which amplifies the input power of the signal. The types of the amplifier are: 2.1 Voltage amplifier: The voltage amplifier increase the input voltage. 2.2 Current amplifier: Current amplifier increase the input current. 2.3 Power amplifier: A power amplifier increase the input power.
Why transistor is used as an amplifier?
We usually employ CE configuration for transistors as amplifiers because it provides large values of current gain, voltage gain and power gain. Moreover, there is a phase-shift of 180 degrees between input and output. It implies the output signal will be an inverted amplified version of the signal given in the input.
When transistor is used as an amplifier?
When the transistor is biased to use as an amplifier, the input signals cause the emitter current to flow, which later contributes to the collector current. This current when flows through the load resistor, it results in a large voltage drop across. This shows that a transistor acts as an amplifier.
What is emitter current?
The emitter current, Ie, of a transistor is the amplified output current of a bipolar junction transistor. There are several ways to find the emitter current, Ie, of a transistor.
