Вот примеры реальных данных, полученных с моей схемой (без введения дополнительного гистерезиса). Отсчеты просто соединены прямыми отрезками.

На не самых низких частотах получается вполне нормально. Это что касается схемы. Возможно в дальнейшем понадобится ее подрихтовать.

А пока все мысли об алгоритме.

На глазок-то по картинке период выделить проще простого.

Разброс длительностей даже между самым длинным и самым коротким получается в пределах 2%.
