A telemetry receiver delivers every sensor's reading to the wrong display. Which fault fits?

  • A.The frame count has slipped by one slot
  • B.One channel's sensor has failed open circuit
  • C.The anti-alias filters have been set too narrow
  • D.The coder's word length has been misconfigured

Answer: A

Everything wrong and nothing missing is the signature of a slot count offset: the receiver is decoding each slot as its neighbour. A failed sensor would corrupt one channel only. Narrow filters would dull every reading without misrouting any. And a word length error would scale the values rather than swap them. A fault that affects every channel equally and in the same way almost always lies in the framing rather than in the channels. Most errors on this topic come from carrying a result across from a neighbouring scheme where it does not hold.
