Amplifier

An electronic device that amplifies sound signals to a point where they great enough to be heard through a speaker.

Amplifier

An electronic amplifier, amplifier, or (informally) amp is an electronic device that increases the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In this sense, an amplifier modulates the output of the power supply to make the output signa...

<microscopy> When the projected image of the microscope is projected less than 250 mm the objective may be moved enough from its usual position (for visual observation) to degrade the image. It can be restored by adding a lens above the ocular to bring the image into focus on the desired plane but with the objective still in its position of b...

amplifier

amplifier, device that accepts a varying input signal and produces an output signal that varies in the same way as the input but has a larger amplitude. The input signal may be a current, a voltage, a mechanical motion, or any other signal; the output signal is usually of the same nature. The most c...

Amplifier

An amplifier is a device or system that changes the amplitude of a signal. The ratio of the amplified signal to the original source signal is commonly referred to as Gain. There are acoustic amplifiers, such as the body of an acoustic guitar or a loudhailer, and electronic amplifiers. In electronics the term amplifier is used to describe the charac...
