slew rate effect on a square wave: red=desired output, green=actual output. In electronics and electromagnetics, slew rate is defined as the change of voltage or current, or any other electrical or electromagnetic quantity, per unit of
Slewing — the amplifier's output voltage reaches its maximum rate of change. Measured as the slew rate, it is usually specified in volts per microsecond. When slewing occurs, further increases in the input signal have no effect on the rate of change of the output.
When slew rate limiting occurs, further increases in the input signal have no effect on the rate of change of the output. Slew rate limiting is usually caused by the input stage saturating; the result is a constant current i driving a capacitance C in the amplifier (especially those capacitances used to implement its frequency compensation ...
These are effects that tend to occur only during parts of a waveform fed through audio amplifiers, that may give rise to audible degradation of the sound quality in music, even when fixed-frequency harmonic distortion tests show low amounts of distortion for a simple sinewave test signal.

While the absence of NFB greatly increases harmonic distortion, it avoids instability, as well as slew rate and bandwidth limitations imposed by dominant-pole compensation in transistor amplifiers. However, the effects of using low feedback principally apply only to circuits where significant phase shifts are an issue (e.g. power amplifiers).
In January 2025, the unemployment rate in the US sat at 4%, a slight decrease from the 4.1% unemployment rate recorded in December 2024. Feb. 7, 2025: Agencies should have plans for federal ...
In electronics engineering, frequency compensation is a technique used in amplifiers, and especially in amplifiers employing negative feedback.It usually has two primary goals: To avoid the unintentional creation of positive feedback, which will cause the amplifier to oscillate, and to control overshoot and ringing in the amplifier's step response.
