ABSTRACT:
A limiter circuit divides the output of a low frequency amplifier into two parts which are respectively high pass filtered, and low frequency amplitude limited. The two parts may be recombined to form an audio output which is freed from clipping distortion at the low end, while the high end is increased. The invention is especially suited for environments such as automobiles, where the ambient noise level may be high.
