STORAGE DEVICE, ELECTRONIC EQUIPMENT, AND METHOD FOR ADJUSTING FREQUENCY BAND COMPENSATION LEVEL
Document Type and Number:
Japanese Patent JP2012191509
Kind Code:
A
Abstract:
To adjust a frequency band compensation level of an equalizer so that it can comply with attenuance in a predetermined frequency band of an input signal.
According to an embodiment, a storage device includes a first equalizer, a second equalizer, and an adjusting means. The first equalizer outputs a second signal that compensates a predetermined frequency band of a first signal transferred via a storage interface by a host. The second equalizer equalizes the second signal, the frequency band of which is compensated, by determination feedback compensation. The adjusting means adjusts a frequency band compensation level of the first equalizer depending on a state of determination feedback compensation performed by the second equalizer.
