1.	What happens when the output of one channel is delayed by one iteration period before comparing with other channels in a quadruplex system?(a) Latency(b) Staleness(c) Aliasing(d) High noiseThis question was addressed to me during an interview for a job.I would like to ask this question from Digital Implementation in division Fly by Wire Flight Control of Avionics
Answer» Correct choice is (B) Staleness Easiest explanation: Data staleness OCCURS when a channel is delayed by, say, one iteration,before comparison with OTHERS. To overcome this problem it is necessary to have some form of time SYNCHRONISATION of the COMPUTER iteration periods.
