Limiter
In electronics, a limiter is a circuit that allows signals below a specified input power or level to pass unaffected while attenuating the peaks of stronger signals that exceed this threshold. Limiting is a type of dynamic range compression. Clipping (audio) is an extreme version of limiting. ==In amplifiers== Bass instrument amplifiers and power amplifiers are more commonly equipped with limiter circuitry to prevent overloading the power amplifier and to protect speakers. Electric guitar amps do not usually have limiters. PIN diodes can be used in limiter circuits to reflect the energy back to the source or clip the signal.〔(【引用サイトリンク】title=PIN Limiter Diodes in Receiver Protectors )〕
