Computerised Sampling and Processing of Continuous Signals by Local Integration and Spline Approximation — •Wolfgang A. Halang — FernUniversität, Fachbereich Elektrotechnik, 58084 Hagen

The continuous sampling and acquisition of experimental time functions by an integrating analogue-to-digital conversion technique is discussed. With special regard to intrinsic noise suppression, the theoretical justification of the procedure’s superiority over point measurement schemes, and an appropriate mathematical method based on positive spline approximation operators for the computer internal representation and processing of empirical functions are established. The technique yields considerable complexity and workload reductions, and eases the time constraints imposed on process control computers.
