An arming system for a weapon, such as a missile, includes a pair of logic elements that output different types of signals upon the occurrence of different pre-arming events. The different types of signals may be, for instance, signals at different frequencies. The different signals are combined in a mixer. The mixed combined signal may be processed by passing it though elements such as a band pass filter and/or a pulse-width modulator/controller. An arming switch is configured to initiate arming when a predetermined condition in the combined signal is detected, such as the presence of a frequency in the combined signal at the difference between the frequencies of the individual signals from the logic elements. By basing arming on characteristics of a mixed combined signal from two logical elements, there are no credible single-point failure modes in the arming system.
