Computers: Microcomputers invade the linear world: Analog interfacing techniques are in demand as microcomputers are exploited in inexpensive equipment for linear applications

The current low cost of microprocessors has justified their use in many areas, particularly in inexpensive equipment that previously could warrant only an analog approach to its implementation. As a result of these linear applications, there exists today a sizable demand for microprocessor analog interfaces — especially low-cost interfaces. These modern analog interfaces use a variety of techniques, geared to specific types of applications.
