Abstract: A digitally controlled angle noise signal generator for generating a signal with precise and accurate noise. The signal generator is formed of a digital noise generator for generating a digital noise signal &thgr;N, and a digital signal generator for forming an internal signal S. The digital signal generator receives the digital noise signal &phgr;N and modulates the internal signal S with the digital noise signal &phgr;N to generate a digitally controlled signal yg=S{&thgr;N}, where is the modulation operator, with precise and accurate noise.
