Изобретение касаетс техники анализа формы импульсных сигналов.The invention relates to a pulse waveform analysis technique.
Известны анализаторы, в которых производитс разложение исследуемого сигнала в р д по различным функци м.

However, such transformations are characterized by a rather slow convergence of a number of decomposition coefficients, which leads to an analysis complication.
