Restoration of Nonlinearly Distorted Magnetic Recordings
An efficient method to restore nonlinearly distorted magnetic recordings is presented. Given the distorted recording and the actual recording device or a model of the record-reproduce process, the original input signal can be computed iteratively. Results from several computer simulations using a variety of nonlinear and linear distortions with different test signals are included. The algorithm converged with fewer than 40 iterations in all simulated restorations.
