Instumention and control MC

Microcomputers are frequently used in industry to record data from varios instrument s and to control Machienary of all types .
There are two important featurs that a microcomputer must have for instrumentation and control applications,the ability to transmit and recieve analog signals and the presence of IEEE 488 bus intergace.
Anolog signals are electrical signals which can change continuosly Digital signals can have one of two levels and nothing in between .All standard micro computers use digital logic but you can buy additional companents that let any general purpose micro computer transmit and recieve analog signals>If your purpose in buying a micro computers is to transmit along signals.If your purpose in buying micro computers that have been built speciffically to process analog signals.
