Patent ID: 7425911

Claim:
A method of generating a first plurality of digital values respectively representing a strength of an input signal at a corresponding plurality of time instances, each of said first plurality of digital values having not more than N-bits, wherein N represents an integer, said method being performed in an ADC (analog to digital converter), said method comprising: sampling said input signal at said plurality of time instances to generate a second plurality of digital values, wherein each of said second plurality of digital values has more than N-bits, said second plurality of digital values containing a first digital value and a second digital value respectively representing a first sample and a second sample of said input signal and having respective values of P and Q when the least significant bits after the Nth position are ignored, wherein P and Q are also digital values; and forming said first plurality of digital values from said second plurality of digital values, wherein said first sample is provided with an integer value greater than P and said second sample is provided with an integer value less than Q in said first plurality of digital values.
