Abstract

Abstract : A multi-channel prediction-error filter technique is developed for suppressing noise on infrasonic signals. The technique uses samples of noise prior to a signal for deriving a Wierner prediction filter that is used to predict the noise during the first motion of the infrasonic signal. A computer program entitled MAXLKH is written to carry out the filtering technique. Application of the technique to actual infrasonic records indicates that noise has some degree of predictability and, hence, an enhancement of the infrasonic signal results. Further tests are suggested to quantify the amount of noise suppression and to optimize technique parameters such as filter length and prediction span. A discussion of the computer program is included.
