摘要： The invention relates to a limiter for limiting the output signal from an amplifier, for example, a video amplifier, which limiter is provided with an amplitude-limiting two-terminal network and an auxiliary amplifier, a first terminal of the twoterminal network being connected to the signal output lead of the amplifier and a second terminal being connected to an auxiliary signal output lead of the auxiliary amplifier, a signal being derived from said auxiliary amplifier which is in phase opposition with the output signal from the amplifier. The output terminals of the limiter are connected to said first terminal of the two-terminal network and to a terminal of fixed reference potential respectively.
