ELIMINATING PULSES FROM MEASUREMENT SIGNALS - CONTEMPORARY APPROACH

Janusz Sawicki

Abstract

Some new methods of elimination of impulsive disturbances are discussed in the paper. The elimination procedures must differ substantially from other filtering methods because of the specific character of disturbance; a wide frequency spectrum results from its shape. The elimination procedure consists of several main steps: prewhitening algorithm, nonlinear transform, inverse filtering. Also some adaptive approaches are mentioned.
