Abstract
According to one embodiment, ao electronic device executes decision feedback-type equalization for input data using a tap coefficient while updating the tap coefficient. The electronic device includes a first memory cyclically receiving a tap coefficient, holing the tap coefficient received, and cyclically outputting the tap coefficient held, and a second memory receiving the tap coefficient cyclically output from the first memory and holding the tap coefficient received. The tap coefficient cyclically output from the first memory is delayed by at least one cycle than the tap coefficient cyclically received by the first memory. The tap coefficient held in the second memory is used for the decision feedback-type equalization in a no-signal period in which no input data exist.

An electronic device for executing decision feedback-type equalization for input data using a tap coefficient while updating the tap coefficient, comprising:
- a first memory cyclically receiving a tap coefficient, holing the tap coefficient received, and cyclically outputting the tap coefficient held;
- and
- a second memory receiving the tap coefficient cyclically output from the first memory and storing the tap coefficient received,
- wherein
- the tap coefficient cyclically output from the first memory is delayed by at least one cycle from the tap coefficient cyclically received by the first memory, and
- the tap coefficient held in the second memory is used for the decision feedback-type equalization in a no-signal period in which no input data exist.
A method for controlling of an electronic device executing decision feedback-type equalization for input data using a tap coefficient while updating the tap coefficient, the method comprising:
- cyclically inputting a tap coefficient to a first memory;
- holing the tap coefficient by the first memory;
- cyclically outputting the tap coefficient from the first memory;
- inputting the tap coefficient to a second memory;
- and
- storing the tap coefficient by the second memory, delaying the tap coefficient cyclically output from the first memory by at least one cycle from the tap coefficient cyclically input to the first memory, and
- using the tap coefficient held in the second memory for the decision feedback-type equalization in a no-signal period in which no input data exist.
