Generation of multidimensional random pulses for radioactivity measurements

Multidimensional binary pseudo-random pulses are extremely useful for the s et-up calibration and testing of radioactivity measuring equipment. A new m ethod of generation of such signals, based on the parting operation of labe led pulse trains, is presented. The concept of a general coincidence ratio is introduced. Digital window comparators and prohibited or permitted state programmers capable of performing the parting operation and controlling th e values of the coincidence ratio are proposed.
