Patent ID: 8018363

Claim:
A method for generating a plurality of output sequences representing an input signal, comprising: (a) initializing a tracking flag; (b) receiving a quantized level value from among a plurality of quantized level values representative of the input signal; (c) if the tracking flag is set, (i) selecting a first output sequence that corresponds to the quantized level value from among a plurality of first output sequences, the plurality of first output sequences being characterized as having a minimum spacing of more than one clock period between transitions in adjacent output sequences, and (ii) clearing the tracking flag; (d) if the tracking flag is not set, (i) selecting a second output sequence that corresponds to the quantized level value from among a plurality of second output sequences, and (ii) setting the tracking flag; and (e) repeating steps (b) through (d) for each quantized level value from among the plurality of quantized level values.
