gainområde
Gainområde is a term used in electronics and signal processing to describe the range of input signal amplitudes over which a device or system maintains its specified gain with acceptable linearity. In this region, the output is approximately proportional to the input, and distortion remains minimal. Outside gainområdet, nonlinear effects such as clipping, saturation, or compression cause the gain to vary with input level, reducing fidelity.
The bounds of a gainområde are set by the device's operating limits. For amplifiers powered by a
Practically, gainområdet is determined from transfer characteristics, often by examining input–output curves. Common metrics related to
In addition to amplifiers, gainområde concepts apply to sensors, ADC front-ends, and control systems, where maintaining
