Võimendis

Võimendis is an Estonian word that translates to "amplifier" in English. An amplifier is an electronic device that increases the power of a signal. This signal can be electrical, as in audio or radio signals, or it can be mechanical, such as with a hydraulic amplifier. The primary function of an amplifier is to take a weak input signal and produce a stronger output signal while maintaining the characteristics of the original signal as much as possible. Amplifiers are fundamental components in a vast array of electronic systems.

In audio systems, amplifiers are used to increase the power of an audio signal from a source, like a CD player or a microphone, so that it can drive loudspeakers. Without an amplifier, the sound produced by loudspeakers would be extremely faint. In radio communication, amplifiers are crucial for both transmitting and receiving signals. They boost the power of the radio waves being sent out and strengthen the weak incoming signals picked up by an antenna. Other applications include musical instrument amplification, such as guitar amps, and in various industrial and scientific instruments where signal amplification is necessary for measurement or control. The concept of amplification is central to modern electronics and telecommunications.
