Abstract
An apparatus generally having a threshold slicer, a state logic device and a converter. The threshold slicer may be configured to generate a (i) first signal having an initial state of a plurality of states in response to a preceding value and a present value from an input signal and (ii) a second signal having a plurality of levels in response to the preceding value and the present value. The state logic device may be configured to generate a third signal having a sequence of the plurality of states starting with the initial state in response to the first signal. The converter may be configured to generate an output signal having the plurality of levels in response to the plurality of states in the third signal.
Claims20
An apparatus comprising:
- a threshold slicer configured to generate a (i) first signal having an initial state of a plurality of states in response to a preceding value and a present value from an input signal and (ii) a second signal having a plurality of levels in response to said preceding value and said present value;
- a state logic device configured to generate a third signal having a sequence of said plurality of states starting with said initial state in response to said first signal;
- and
- a converter configured to generate an output signal having said plurality of levels in response to said plurality of states in said third signal.
An apparatus comprising:
- means for generating a first signal having an initial state of a plurality of states in response to a preceding value and a current value from an input signal;
- means for generating a second signal having a plurality of levels in response to said preceding value and said current value;
- means for generating a third signal having a sequence of said plurality of states starting with said initial state in response to said first signal;
- and
- means for generating an output signal having said plurality of levels in response to said plurality of states in said third signal.
A method of processing an input signal, comprising:
- (A) generating a first signal having an initial state of a plurality of states in response to a preceding value and a current value from said input signal;
- (B) generating a second signal having a plurality of levels in response to said preceding value and said current value;
- (C) generating a third signal having a sequence of said states starting with said initial state in response to said first signal;
- and
- (D) generating an output signal having said plurality of levels in response to said plurality of states in said third signal.
