Arbitrary equalization with simple LC structures

Equalization for magnetic recording with LC filters was reported in 1963 [1], and since then many other approaches have been used to alter the readback signal to reduce error, These ideas have been extended to arbitrary input-arbitrary output filters which are realized as LC structures without mutual inductance. An asymmetrical signal from an isolated pulse is equalized to become optimum in the linear Van der Maas sense [2], The change in the signal to noise ratio as a result of equalization is computed as a function of pulse slimming.
