Abstract

When two series of randomly occurring pulses on lines 1 and 2 are "OR"ed, as at A, and used as an analyzer input 3, it is difficult to determine the input line from which the signal originated.

Identifying Multiscaling Events

When two series of randomly occurring pulses on lines 1 and 2 are "OR"ed, as at A, and used as an analyzer input 3, it is difficult to determine the input line from which the signal originated.

By using the circuit modification at B, the input channel is identified by determining whether the count is even or odd. The units digit one bit signal from the counter to the memory is disconnected. A latch 6 which will hold the memory units digit one bit always on when a pulse occurs on channel 2, and always off after a pulse occurs on channel 1, will cause the count to be odd or even to indicate a channel 2 pulse or a channel 1 pulse, respectively. The count thus indicated will vary not more than one unit from the true count. Similarly, four series of pulses could be identified by sacrificing the two low-order digit bits.
