On the Design of Pulse Peak Stretchers

This paper deals with the design of feedback peak stretchers, its main aim being that of ensuring both linearity and absolute accuracy as well as a fairly low degree of sensitivity to the input shape. A preliminary discussion on the limitations of the blocks which constitute the feedback loop of the stretcher is followed by suggestions for their realization. The conclusion of a short theoretical analysis are summarized, for an easier choice of the proper solution according to the various applications. Finally, different schemes of stretchers are given, which are believed to satisfy most of practical needs, and the results of the experimental tests are shown.
