Abstract
The 1-D Teager algorithm can be used to perform mean weighted highpass filtering with relatively few operations. We propose a generalization of the Teager algorithm. The modified algorithm allows us to adjust the dependence of the highpass output on the local mean. The derivation and interpretation of the modified algorithm is presented. Finally, the response of several implementations to a test input is presented.
