Abstract
A first-order signal generator (135). The generator comprises a shift register (210′) having a number N of bit positions. Each bit position is operable to store a binary value, the shift register operable to shift the binary value at each of the bit positions. The generator also comprises circuitry for tapping selected ones of the bit positions and circuitry for applying a function (220′) to each binary value in the selected ones of the bit positions to provide a function output. The generator also comprises circuitry for coupling the function output as an input to one of the bit positions. Lastly, the generator also comprises circuitry (230′) for outputting a first-order noise signal by coupling, as a twos complement number, each binary value in a plurality of the bit positions.
