limiter circuit (13) to increase the dynamic hysteresis insensitive to distortion at the output of the circuit in response to an input signal.the limiter circuit (13) includes a positive peak detector (15) and negative (17).weighted averages are obtained from both the positive and negative peaks, preferably by means of a voltage divider network (18).the first entry to a comparator circuit receives the input signal to the limiter circuit (13).different voltages from the voltage divider network (18) is applied to the second input of the comparator circuit (21) in such a way as to create a hysteresis effect with dynamic circuit comparateur (21). the different voltages are selected from the output voltage of the comparator circuit (21) by means of an analog switch (19).the circuit includes a voltage comparator (21) fixed to stabilize the valve hysteresis circuit (13) for input signals of low voltage.
