Abstract:
A digital interpolating system for transmitting a digital output value within a first range defined by a minimum digital value and a maximum digital value, comprising:digital circuitry configured to receive said maximum digital value, said minimum digital value and a digital control value within a second range defined by a minimum control value and a maximum control value, said digital circuitry further configured to output said digital output value based on said digital control value, wherein said digital output value corresponds to a first sum divided by a second sum,wherein said first sum corresponds to a first value, a second value, a third value, and a fourth value added together and said second sum corresponds to said maximum control value added to a value of one, andwherein said first value corresponds to said maximum digital value multiplied by said digital control value, said second value corresponds to said minimum digital value multiplied by a one's complement of said digital control value, said third value corresponds to a fraction of said minimum digital value, and said fourth value corresponds to a fraction of said maximum digital value.
