Võimendusastmega

Võimendusastmega, a term often encountered in electronics and audio engineering, refers to the gain stage of an amplifier. It is essentially a section of an amplifier circuit responsible for increasing the amplitude of an electrical signal. Each võimendusastmega takes an input signal, amplifies it, and passes it on to the next stage or to the output. The number of võimendusastmega in an amplifier can vary significantly depending on its design and intended application.

In a typical audio amplifier, for example, there might be several võimendusastmega. The initial stages are often designed to amplify weak input signals, such as those from a microphone or a turntable, to a level that can be further processed. Subsequent stages may provide higher power amplification to drive loudspeakers. The characteristics of each võimendusastmega, such as its voltage gain, current gain, bandwidth, and noise performance, collectively determine the overall performance of the amplifier. Understanding the role of each võimendusastmega is crucial for designing, analyzing, and troubleshooting amplifier circuits. The term highlights the modular nature of amplification, where signal processing is broken down into discrete steps of signal enhancement.
