Question

(a) Latency

(b) Staleness

(c) Aliasing

(d) High noise

This 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 1

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.
