IRE transactions on bio-medical electronics
A two-channnel, three-decade counter incorporating digital logic for selecting nerve impulses by amplitude and time interval of occurrence is discussed. The count of the number of selected impulses, their time interval or time of occurrence is printed out photographically superimposed on the oscilloscope trace of the impulses. Printed circuit logic modules facilitate construction, maintenance, change of function or expansion of capacity.
