Editing Circuit reliability

'''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 engineering|reliability]] is given by 
:<math>T_s = T_a + T_o</math> 
where <math>T_o</math> is the circuit total outage time, <math>T_s</math> is the circuit total scheduled time, and <math>T_a</math> is the circuit total available time.
In addition, circuit reliability is the expected lifespan of operation of a functioning system under nominal conditions.
