Võimendussirged

Võimendussirged is a term used in Estonian electrical engineering and physics to refer to amplifier gain curves or characteristics. These curves graphically represent how the output signal of an amplifier changes in relation to its input signal or other parameters such as frequency or voltage. Typically, a võimendussirge illustrates the voltage or power gain of an amplifier.

These curves are crucial for understanding an amplifier's performance. For instance, a flat võimendussirge over a wide range of frequencies indicates a good frequency response, meaning the amplifier can amplify signals of different frequencies equally well. Deviations from a flat line at higher or lower frequencies suggest limitations in the amplifier's bandwidth.

Other common types of võimendussirged include those showing gain versus input voltage, which helps in identifying the linear operating region of the amplifier and the point at which distortion begins to occur (saturation). They can also depict gain versus temperature or other environmental factors. Analyzing these curves allows engineers to select appropriate amplifiers for specific applications and to predict their behavior under various operating conditions. The shape and features of a võimendussirge are determined by the amplifier's design, including the active components used and the surrounding circuitry.
