Dielectric loss analysis of of toroid MnZn ferrite core

Two types of relaxation polarisation are combined to analyse the frequency spectrum of the complex permittivity of MnZn ferrite. The dielectric loss o f the toroid core has been calculated based on this polarisation model. Res ults show that the dielectric loss accounts for 25% of the total loss in th e megahertz region.The effect of whitening the input data in a multilayer p erceptron-based decision feedback equaliser (DFE) is evaluated. It is shown from computer simulations that whitening of the received data employing ad aptive lattice channel equalisation algorithms improves the convergence rat e and bit error rate performances of multilayer perceptron-based DFEs.
