Operational Amplifier Question & Answers
Voltage and power are the two major classifications of amplifiers and the classification is done on the basis of the comparison made according to the characteristics of applied input and generated output signal. The crucial difference between a voltage amplifier and a power amplifier is that a voltage amplifier increases the voltage level of the applied input signal. As against, a power amplifier is the one that boosts the power level of the input signal. An amplifier is an electronic device that boosts the level of the signal present at its input and provides the raised but identical signal at the output. Thus, it is a device that serves the purpose of amplification. The factor that determines the level of the amplification given by the amplifying unit is known as the gain of the amplifier. Generally, various applications require very large output signals which a single amplifying unit fails to provide.
