Signal source with a polyphase filter |
| 摘要 |
<p>The signal source has a local oscillator (5) with a frequency divider (6) connected. Two signal outputs are output in phase and quadrature (Id,Qd). A polyphase filter (7) is connected to the frequency divider output producing two sinusoid signals (Is,Qs) at a multiple of the filter input frequency.</p> |
