Inverse Filter
Inverse Filter :
(n). Formation Evaluation. Generally, a finite impulse response (FIR) filter that has been designed to transform the usually irregular vertical response functions of raw measurements into a smooth, well-behaved response function such as a Gaussian response or a Kaiserwindow function. The criteria for designing inverse filters can include vertical response, depth of investigation and near-field(cave effect) response. Inverse filters have been used for many years to improve the response of induction arrays. See: deconvolution, response matched
