  • Angle quantization using log division
    Patent number: 6518897
    Abstract: A system to perform angle quantization includes a log ROM lookup table to provide a log of a real input (10) of a signal and a log of an imaginary input (20) of the signal. A subtractor (100) computes the difference between the log of the real input and the log of the imaginary input to provide a difference (102) equivalent to a division of the inputs, and a ROM lookup table (110) determines a phase from the difference.
