  • Reduced size phase-to-amplitude converter in a numerically controlled oscillator
    Patent number: 4855946
    Abstract: A numerically controlled oscillator employing a 1/2 least significant bit (LSB) phase offset and a negative 1/2 LSB amplitude offset of data samples in memory devices for improved quadrant replication. Also, fine values are added or subtracted to the coarse values further reducing the amount of data needed in memory and further reducing the size of the phase-to-amplitude converter.
