Description	The article deals with signals from systems involving hydrogen-filled proportional counters intended for neutron detection and spectrometry. It provides a theoretical basis describing the origin of these signals and their properties. The article presents a method of discrimination between neutron radiation-related and other events as well as its potential to widen the energy range of neutron spectrometry. Also the measurement apparatus and signal processing approaches are described. Moreover, the article lists certain data from the testing of proportional counters to serve as a proof of their correct operation.
