UN APARATO PARA DETERMINAR SI HA OCURRIDO EL NUMERO DE IM- PULSO APROPIADO DENTRO DE CADA GRUPO DE UNA SERIE DE GRUPOS DE IMPULSOS SEPARADOS.

摘要

Emitter pulses generated in groups are checked to determine whether or not the correct number are present in each group. The pulses are introduced to a counter, the contents of which is inspected by appropriately timed gating whenever a count equivalent to a full pulse group should be present. The inspection circuitry is controlled so as to accommodate acceptable odd spacing in the pulse groups.
