äänivahvistimen
Äänivahvistin, commonly known as an amplifier, is an electronic device that increases the amplitude of an audio signal. This amplification is crucial for making audio signals loud enough to be heard through speakers or headphones. Without an amplifier, the electrical signals produced by sources like microphones, musical instruments, or audio players would be too weak to produce audible sound.
Audio signals are essentially fluctuating voltages. An äänivahvistin takes this weak, fluctuating voltage and uses an
There are various types of äänivahvistimet, categorized by their design and intended application. Common types include
The quality of an äänivahvistin is often judged by its ability to reproduce the original audio signal
