Abstract

Abstract ABSTRACT Apparatus for obtaining a histogram of the separation time between successive events. The apparatus is comprised of a time base (3) whose output is connected to a first set of decade counters (5.1 to 5.X) which are each associated with the detection means of the counter that keeps track of the state of the counter which counts and which has not yet overflowed, a corresponding set of AND gates (10.1 to 10.X) each with an input connected to the output of the corresponding detection means (5.1 to 5.X) and the other input connected to the source of events (2). The CLR input of the detection means is connected to the source (2), through a delay circuit (6). The output of each AND gate (10.1 to 10.X) is connected to a second set of decade counters (111.1 to 11X.1), each associated with a memory. A timer (4) has its input connected to the time base (3) and its output to the transfer control means of the contents of each counter of the second set (111.1 to 11X.1) to its associated memory. Reading means (12.1 to 12.X) read the contents of the memories to a recording apparatus. A second delay circuit (9) has its input connected to the output of timer (4) and its output to the CLR inputs of the counters. The reading means is comprised of a set of multiplexers whose inputs are selectively connected to the outputs of the memories.
