    Application specific integrated circuits (ASICs) have been one of the electronics success stories of the 1980s. The rise in their complexity means that chips are now so complex that it is no longer feasible for a test engineer to understand the design at the level of detail required to generate a test program. ASIC designers are increasingly assuming responsibility for test program development. Fa... View full abstract»

    A large proportion of the UK trunk communications for data and telephony needs are now met by single-mode optical fibre cable systems. Network planners need to increase the capacity of optical systems but this is becoming increasingly difficult. The preferred way to increase the distance over which an optical cable can operate is to place optical amplifiers in the line. The author looks at how opt... View full abstract»
