Abstract

A smoothing device for signals in real time uses a formula for sampling an analogue signal which is a function of the parameter (t) for certain discrete values of t, to give a constant line interval. This device has a numerical analogue converter which converts signal amplitudes corresponding to the various discrete values of t into given numerical values. This device has a K shift register a sequential register input arrangement and an electronic adding and subtracting system. An arrangement of K values is calculated by a pair of formulae using certain sums of the zero, second and fourth powers of whole final numbers and using the corresponding different moments.
