Abstract
The article describes a detector for physiological phenomena, e.g., the QRS-complex, having a trigger accuracy of 0.5 ms. The configuration to be recognized first is preprocessed then fed into a pair of amplifiers with adjustable gain and offset, representing the upper and lower contour-limit derived from the actual signal. These signals are sampled and A/D converted, then stored in two memories during the ``read´´-operation.
