This nonlinearity may be caused by heat due to power dissipation or by overdriving the active device beyond its linear region. It is a large-signal phenomenon of circuits. See more Gain compression is relevant in any system with a wide dynamic range, such as audio or RF. It is more common in tube circuits than transistor circuits, due to topology differences, possibly causing the differences in audio … See more Clipping, as a form of signal compression, differs from the operation of the typical studio audio level compressor, in which gain compression is not instantaneous (delayed in time via attack and release settings). Clipping destroys … See more • Third-order intercept point • Dynamic range compression See more A tube radio or tube amplifier will increase in volume to a point, and then as the input signal extends beyond the linear range of the device, the effective gain is reduced, altering the shape of the waveform. The effect is also present in transistor circuits. The extent of the … See more Gain compression in RF amplifiers is similar to soft clipping. However, in narrowband systems, the effect looks more like gain … See more Power compression is a form of gain compression that takes place in loudspeaker voice coils when they heat up and increase their resistance. This causes less power to be drawn from the amplifier and a reduction in sound pressure level. See more Webthat is greater than the RF input power. Therefore, conversion gain is specified instead of conversion loss; it is equal to the ratio of the IF single-sideband output power to the RF input power, expressed as a positive number in dB.
