Digital Equalization on the Stationary Head Type DAT
On the DAT, recording data are around 2.4MBPS as L and R channel signals at a 44.1kHz sampling rate. This is attained not only by dividing data into 20 tracks but also doing high density recording, 64KBPI. In this high density recording, equalization must be provided to the reproduced signals because of their intersymbol interference. We investigated the equalizer with digital signal processing. This equalizer is constructed using a transversal filter. In designing this equalizer we applied the mean-square error method to decide tap coefficients, assuming that the superposition of magnetic transition on tape is satisfied. First, details of this equalizer circuit and its decision method are mentioned. Then the experimental results are reported. As a result, superposition of impulse response is well satisfied and it is able to design the digital equalizer easily.
