In many applications it is desired to generate pulses which correspond to predetermined characteristics of an input signal, such as is peaks. This may be achieved by differentiating the input signal and supplying the differentiated signal through a high gain comparator which then controls a pulse generator. The output signal of such a comparator has a logic-level transitions at every peak of the input signal. The transitions arise or go positive for a negative peak and go negative for a positive peak. As a function of the shape and the other characteristics of the input signal, there may be an unwanted transition caused by noise, intersymbol interference and the like. Such unwanted transitions can result in unwanted output pulses.
