Two methods are considered for filtration of a discrete signal. The first method consists of using an integrator to convert the discrete signal to a continuous quantity with subsequent filtration by a continuous filter. The second method consists of adding the values of the signal taken at discrete instants during a certain time interval. Block diagrams are given of the devices used for filtration by both these methods. A comparison of these two filtering methods shows that the second method gives higher accuracy and requires less time for determining the value of the constant components.
