摘要： An interrogation system in which comparison circuits determine lead or lag of an interrogation code in the answering apparatus, i.e., transponder, and provide a compensating correction. The system employs time dependent differing interrogation codes which are successively transmitted from an interrogation apparatus to one or more answering apparatuses. Time dependent differing answer codes, logically related to the interrogation codes, are employed to indicate a friendly answer. The answer codes are generated and stored as past, present and future time codes. Lead or lag of the clock of the answering apparatus with respect to the interrogation apparatus is determined by a comparison of stored and received interrogation codes so that a resetting of the code program and/or an adjustment of the clock can be performed to achieve synchronism.
