CORRECTION OF QUADRATURE ERROR |
| 摘要 |
<p>The invention relates to an analog quadrature demodulator (100), which comprises analog domain means for splitting an incoming signal into an in-phase (I) branch signal and a quadrature (Q) branch signal and an analog domain correction circuitry (106, 107) for controllably causing the in-phase (I) branch signal and the quadrature (Q) branch signal to co-operate with each other via said correction circuitry (106, 107) so as to correct the quadrature error.</p> |
