DIGITAL SMOOTHING FILTERS,
Abstract
Digital filters with infinite transient time have a low order of astatism, i.e., high dynamic error. The present article offers a method for synthesizing digital filters with infinite transient time which can smooth down and also transform the signal; their order of astatism can be made sufficiently high. A filter with an exponential weight function and an infinite transient time is equivalent (as far as reproduction of linear signal and smoothing of noise are concerned) to a filter with finite transient time that has a rectangular weight function. Block diagrams of the new filter for 0, 1, and 2 orders of astatism are shown.
