ABSTRACT:
Arrangement for measuring the ratio between a number of sequential events occurring in a first series of events and a number of events in a second series of events, each series activating a pulse generator (P1, P2) included in the arrangement. The arrangement further comprises a counter (C) which is stepped forward by the pulses generated by the pulse generator (P1) controlled by the first series of events. A multiplying arrangement (D1) receives the counter value of the counter (C) and multiplies this value by a factor m where m indicates a selected part of the received counter content. The multiplying arrangement (D1) receives on a control input, a pulse from the pulse generator (P2) controlled by the second series of events. When the arrangement (D1) receives that pulse it feeds a signal to a subtracting input of the counter (C), which signal reduces the counter content by a number of steps corresponding to the multiplication result, so that the counter content varies between two limit values. An indicating unit (I) is arranged for indicating the difference between this two limits thus showing the quotient between the number of events of the two series of events.
