Võimendusastmed

Võimendusastmed refer to the distinct stages within an electronic amplifier where the signal undergoes amplification. Each stage is designed to increase the amplitude or power of the signal by a specific factor, known as its gain. These stages are typically cascaded, meaning the output of one stage becomes the input of the next, allowing for a significant overall amplification. Commonly, amplifiers consist of multiple võimendusastmed to achieve the desired level of signal enhancement. The design and characteristics of each võimendusaste are crucial for determining the amplifier's performance, including its frequency response, distortion levels, and power output. Early stages might focus on voltage gain, while later stages could be optimized for power delivery. The specific number and type of võimendusastmed employed vary greatly depending on the amplifier's intended application, such as in audio systems, radio frequency circuits, or instrumentation. Understanding the role of each võimendusaste is fundamental to analyzing and designing amplification circuits.
