Wave packet`s temporal position determining method for e.g. spirometer, involves computing sum of product as product from value of comparison function and measurement value, and computing temporal position from sum of product

摘要

The method involves scanning the wave packet to multiple point of time and producing a measurement value for each point of time. A sum of product is computed, where the product is computed for a determined point of time as a product from a value of a comparison function and the measurement value by a microprocessor (9). The temporal position of the wave packet is computed from the computed sum of product.
