Arrangement for measuring the ratio between a number of events occurring after each other in a first and a second series of events

Abstract From the Canadian patent

The invention concerns an arrangement for measuring the ratio between a number of events occurring after each other in a first series of events and a number of events in a second series of events, each series activating a pulse generator included in the arrangement. The arrangement further comprises a counter which is stepped forward by the pulses generated by said pulse generator controlled by said first series of events. A multiplying arrangement receives the counter value of said counter and multiplies this value by a factor m where m indicates a selected part of the received counter content. The multiplying arrangement receives on a control input, a pulse from said pulse generator …
