Circuit reliability (also time availability) (CiR) is the percentage of time an electronic circuit was available for use in a specified period of scheduled availability. Circuit reliability is given by where T o is the circuit total outage time, Ts is the circuit total scheduled time, and T a is the circuit total available time.
In addition, circuit reliability is the expected lifespan of operation of a functioning system under nominal conditions.
Famous quotes containing the word circuit:
“The Father and His angelic hierarchy
That made the magnitude and glory there
Stood in the circuit of a needle’s eye.”
—William Butler Yeats (1865–1939)
