Phase offset calculation method and phase offset circuit |
摘要 |
The phase offset circuit of the present invention realizes a phase offset of a multiple of 90° by inverting the sign of signed binary data first, and then adjusts the amplitude of the signal. Finally, the phase offset calculator realizes a phase offset with a rotation angle smaller than 90° (for example, a fixed 45° offset).
