Hint: Amplification is the process of increasing the strength of the signal. The amplifier is the device that amplifies the signal. the amplifier used to improve the strength of the signal without changing the shape of the original signal.
Complete step by step solution:
An amplifier is used to describe a circuit that increases the strength of the input signal, but not all amplifiers are the same as they are classified according to their circuit configurations and methods of operation.
The classification of an amplifier is Operational Amplifiers and Small Signal Amplifiers up to Large Signal and Power Amplifiers. The amplifier classification depends upon the size of the signal, large or small, its physical configuration, and how it processes the input signal, which is the relationship between the input signal and the current flowing.
Suppose if we have an electronic signal available but we need to “strengthen.” We use an amplifier to boost up the weak input signal. For Example, the headphone signal from smartphones needs to be amplified to make a speaker loud to hear.
The input signal is defined by voltage, current, and power. An amplifier can generate the voltage bigger at the same current, the current gets strengthen without affecting the voltage, or it can change both the voltage and current
The amplifier principle is to generate an output signal that is a replica of the input signal with an increased higher magnitude.
Note:
Amplifiers strengthen or boost the weak signal without changing any input or information.
Negative feedback is used in amplifiers. The negative feedback is due to decreasing the gain of the amplifier.
If the gain is decreased, noise also decreases so system stability increases.
