Background
In 1950 and 1960, electronic, space, avionics are invited to a simple stand-alone. Navigation, communications, air traffic, and the poster is connected to analogue systems. Often these systems consist of several lots, or part of systems connected to a single system. Several issues connected to the system, links point to point. Analog signals were in many cases, the timing and resolution of interrupter signal contact.
These areas are Opera relief is available and weight restrictions aerospace and deliberate. Because the system is new planes lamented pressure, complicated wiring and increases the total weight of the aircraft. In late 1960 and early 1970, it was necessary for the exchange of information between different systems to reduce the number of black squares are needed to evaluate each system. One of the sensors, which sense is always right, and information confirm that the information on the 1553 navigation system of the gut, the flight and the pilot trafficked.
However, electronic technology is still largely analog, and hence the location of the sensors are not black boxes to reduce the total fees for your nest is a sign of mice, the Son and connectors. Moreover, functions and systems into a nightmare integration later, other compounds of Dun, a certain brand of a potential impact on the system. Moreover, the scoring loop point that the 1553 system is the source of the signal is usually modified to provide additional facilities for the production subsystem, delivery of young.
Lavenant digital technology, digital technology, in 1970, he said, digital computers have found their way into electronic systems and subsystems. They offer power and convenience, the highest growth than their analog predecessors. Although the data signals, input and output lenitive and receive analog systems are still largely in kind. This led to the composition of a single central Dorine (usually only one or two), second to analog systems and subsystems intermarriage complex and expensive digital converter and interface.
As time and technology advance, Davion has become increasingly digital. And beyond the microprocessor, are things really. Numerical advantage of this demand should be reduced and the analog signal, where? Need to change. Transmission of data to users in digital format, to improve the distribution of sensor data. Another advantage is that digital linformazione sent in two directions, and analog data to work in both directions. Number of parallel data used to dinterconnexions device driver and receiver circuits of the black boxes.
