Which system has replaced the CADC by using smaller and cheaper microp

1.	Which system has replaced the CADC by using smaller and cheaper microprocessors?(a) Navigational system(b) Distributed air data system(c) FADEC(d) Inertial systemI got this question by my college professor while I was bunking the class.My query is from Air Data Computers topic in portion Air Data Systems, Altitude and Heading Reference of Avionics
Answer» The correct choice is (b) DISTRIBUTED air DATA system The best explanation: With the advent of smaller and CHEAPER microprocessors, it became possible to pack them with probes and transducers. The result is a distributed air data system that REPLACES the CADC. A key feature is the packing of signal processing units with or adjacent to the probes.
