Forforstærkerenhed
Forforstærkerenhed, often translated as preamplifier unit or simply preamp, is an electronic circuit that amplifies weak electrical signals, typically from a sensor or a low-level audio source, to a level suitable for further processing or transmission. This amplification is crucial because many signal sources produce outputs that are too small to be directly measured or utilized by subsequent stages of an electronic system. The primary function of a forforstærkerenhed is to increase the amplitude of the input signal without significantly distorting it or introducing excessive noise.
These units are commonly found in a wide range of electronic devices. In audio systems, preamplifiers are
A key characteristic of a forforstærkerenhed is its high input impedance and low output impedance. High input
